2. Evaluation board configuration

This section describes the configuration options and the connectors on the EVB.

2.1 Board layout The EVB provides access to all of the pins of the MCU and provides configuration of the power supply and operating voltage of the MCU. The EVB provides different groups of connectors depending on the developer requirements. Note that many of the signals are replicated on more than one connector. Some connectors provide direct access to the pin of the MCU and some provide physical interfaces to different bus standards. The MCU itself is housed in a ZIF socket. The board outline is shown in Figure 1.

2.2 EVB Description Each configuration block of the EVB is described in the following sections.

• MCU & Clock configuration controls the choice of clock source for the MCU. The MCU can be replaced; take care to correctly orientate the MCU and ensure that the socket pins align with the MCU pins. See 2.3.

• Power configuration controls the source of power for the MCU. See 2.4 for the configuration of the power supply.

• The Reset Switch SW1 asserts the RESET I/O on the MCU. • Serial Port configuration connects the MCU pins to the physical interfaces of the serial ports.

Depending on the usage of the port lines it may be necessary to disconnect these jumpers for correct operation. See 2.5 for the configuration of the serial ports and a description of their associated connectors.

• Port D switch and Port C LEDs provide simple I/O to the MCU. See 2.6. The port pin headers and expanded bus connector are described in the following sections

• The BDM Header is the primary debug interface to the MCU. This follows the standard 6-pin convention used throughout Freescale development hardware. See 2.7

• The Expanded bus connector contains all of the port lines required for the expanded bus. See 2.8.

• The Display headers contain all 36 pins of the on-chip LCD driver as well as an assortment of functionality useful for driving TFT, VFD and other display types. See 2.9.

• The Motor header contains the high current PWM ports from the MCU as well as an SPI that may be useful to have when driving motors. See 2.10

2.3 MCU & Clock configuration 2.3.1 Oscillator J27

The oscillator design allows selection between a crystal and an on-board oscillator. The PLL components are chosen to have an optimal configuration with an oscillator of 4MHz and a bus clock of 40MHz. Figure 2 describes the configuration. J27 selects between a 4MHz crystal and a logic-level oscillator. By default the MCU will choose a loop-controlled oscillator option (used by crystal only). To select the full-swing oscillator mode that is required for an external clock then change the state of port PE7 at reset to be a logic 1. For factory configuration install a jumper on J27 between pins 2 & 3.

Mode slection J14, J26, J30 The board allows selection of any MCU mode. See Figure 3 for configuration details. For factory configuration do not install jumpers on these headers.

Figure 3 Mode selection

2.4 Power configuration The factory configuration of the board supplies all power pins from the main +12V connector.

+12V power connector P3 The power connector is a two terminal barrel connector as used on the S12XE base board. This is a 2.1mm connector with centre pin a nominal +12V. Minimum current capability should be approximately 200mA.

Fuse F1 Fuse F1 provides protection for the board in the event of over current on the main power supply input. Be careful not to exceed the 250mA value or replace the fuse with a higher value if required for additional circuitry. This fuse does not protect the alternate power inputs.

Switch SW2 Switch SW2 connects to +5V supply to the board.

Important Note SW2 does not switch the input voltage +12V, instead it switches the generated +5V to the components o the EVB including the EVB. The +12V is therefore directly connected to the interface connectors. Take care when connecting circuitry to the +12V on these connectors and the circuitry on the EVB such that you do not power the EVB via these logic connections. It is recommended that you switch the +12V external to the EVB if you are using the EVB as part of a sub-assembly which includes active circuitry on the display, motor or expanded bus connectors.

Trimmer R1 This trimmer adjusts the voltage supply for the board from approximately 3.3V to 5V. For the 9S12XHZ512 the operating range of the MCU is from 4.5V to 5.5V.

VLCD configuration J12 The contrast of an attached LCD module will be affected by VLCD. This has connections as shown in Figure 4. For the factory configuration place a jumper on J12 between pins 1&2.

2.5 Serial port configuration 2.5.1 CAN interface P10, P11, J35, J36, J37, J38

To use the CAN interface CAN0 connect jumpers to J35 and J36. To use the CAN interface CAN01 connect jumpers to J37 and J38. Take care to avoid conflicts if these port lines are used on other connectors. The CAN connectors P10 and P11 are four pin Molex 39-30-3047 connectors as used on the Softec S12XD Starter Kit. The pin out is shown in Figure 6.

To use the LIN interface SCI0 connect jumpers to J33 and J34. To use the LIN interface CAN01 connect jumpers to J31 and J32. Take care to avoid conflicts if these port lines are used on other connectors. In particular SCI0 shares pins with RS232 connector so that jumpers J2 & J34 (PS0) and J1 and J33 (PS1) should not normally be installed at the same time. The LIN connectors are four pin Molex 39-29-5043 connectors as used on the Softec S12XD Starter Kit. The pin out is shown in Figure 7.

The position of the signals on the connector is shown in Figure 9.

2.8 Expanded Bus Connector P9 The external bus connector matches the connector on the S12XEP100 EVB. The connector is a female 96-way, 3-row DIN41612 90° edge connector. The connector carries the following signals:

Figure 8 BDM connector pin out

2.7 BDM Connector H8 This connector provides access to the BGND debug pin on the MCU as well as other essential debugging signals (power and reset). The pin out is shown in Figure 8.

2.6 Port D switch and Port C LEDs J16, J18, J19, J21, J22, J24, J25, J28 Port D has a simple 4-way DIP switch connected to ports PD0 to PD3. When closed these switches connect each port pin to VDD via a 3.3kΩ resistor. Each pin on Port C is connected to a jumper that allows connection to an LED and protection resistor. The cathode of the LED is connected to VSS. To enable the LED fit the appropriate jumper: J16 (PC0), J18 (PC1), J19 (PC2), J21 (PC3), J22 (PC4), J24 (PC5), J25 (PC6), J28 (PC7).

• port L[0:2] (AD[8:10]) • port AD • port S[4:7] • port T, port P • ports P6, S2, P7 and M1 (CS[0:3]) • port E[2:5] (RE, LSTRB, ECLK, WE) • port K (ADDR[16:22), EWAIT]) • port D (DATA[0:7]) • port C (DATA[8:15]) • port B (ADDR[0:7]) • port A (ADDR[8:15])

To use the RS232 interface connect jumpers to J1 and J2. Take care to avoid conflicts if these port lines are used on other connectors. In particular SCI0 shares pins with RS232 connector so that jumpers J2 & J34 (PS0) and J1 and J33 (PS1) should not normally be installed at the same time. The RS232 connector is a female DB-9 connector connected to SCI0. The pin out is shown in Error! Reference source not found..

SW2 does not switch the +12V on this connector. The +12V is therefore directly connected to this interface connector. Take care when connecting circuitry to the +12V on this connector and the circuitry on the EVB such that you do not power the EVB via these logic connections. It is recommended that you switch the +12V external to the EVB if you are using the EVB as part of a sub-assembly which includes active circuitry on the display, motor or expanded bus connectors.
