Installation And Setup

Power Oak supplies.

PWR jack connection provides power input from the supplied wall plug power source. Typical

input is +12VDC. The PWR jack provides a center positive terminal and ground outside sleeve.

The jack accepts 2.1mm inside x 5.5mm outside power plugs.

2.2.4 Selecting Terminal Baud Rate

The serial channel SCI0 of the MPC564 is used for serial communication and has a built in baud

rate generator. A number of baud rates can be programmed. On power-up or manual RESET, the

dBUG ROM monitor firmware configures the channel for 19200 baud. Once the dBUG ROM

monitor is running, a SET command may be issued to select any baud rate supported by the ROM

monitor. Refer to Chapter 3 for the discussion of this command.

2.2.5 The Terminal Character Format

The character format of the communication channel is fixed at power-up or RESET. The default

character format is 8 bits per character, no parity and one stop bit with no flow control. It is

neccessary to ensure that the terminal or PC is set to this format.

2.2.6 Connecting the Terminal

The board is now ready to be connected to a PC/terminal. Use the RS232 serial cable to connect

the PC/terminal to the MPC564EVB at COM-1. The cable has a 9-pin female D-sub terminal

connector at one end and a 9-pin male D-sub connector at the other end. Connect the 9-pin male

connector to connector COM-1 on the MPC564EVB board. Connect the 9-pin female connector

to one of the available serial communication channels normally referred to as COM1 (COM2, etc.)

on the PC running terminal emulation software (such as AxIDE, TeraTerm or Hyperterminal). The

connector on the PC/terminal may be either male 25-pin or 9-pin. It may be neccessary to obtain

a 25-pin-to-9-pin adapter to make this connection. If an adapter is required, refer to Figure 2-2

which shows the pin assignment for the 9-pin connector on the board.

2.2.7 Using a Personal Computer as a Terminal

A personal computer may be used as a terminal provided a terminal emulation software package is

available. Examples of this software are AxIDE, TeraTerm, PROCOMM, KERMIT, QMODEM,

Windows 95/98/2000 HyperTerminal or similar packages. The board should then be connected as
