MPC564EVB Jumper and Switch Setup
described in Section 2.2.6, “Connecting the Terminal.”
Once the connection to the PC is made, power may be applied to the PC and the terminal emulation
software can be run. In terminal mode, it is neccessary to select the baud rate and character format
for the channel. The character format should be 8 bits, no parity, one stop bit. (see Section 2.2.5,
“The Terminal Character Format”.) The baud rate should be set to 19200 and XON/XOFF flow
control should be turn on. Power can now be applied to the board.
Figure 2-2. Pin assignment for female (Terminal) connector.
Pin assignments are as follows.
Pin 1, 4, and 6 = group connected for DTR/DSR flow control null back to host
Pin 2 = TXD output (RS232 level)
Pin 3 = RXD input (RS232 level)
Pin 5 = Ground/Vss/Common
Pin 7 and 8 = group connected for RTS/CTS flow control null back to host
Pin 9 = open
2.3 MPC564EVB Jumper and Switch Setup
Jumper settings are as follows:
Note ‘*’ is used to indicate that default setting.
‘**’ is used to indicate mandatory setting for proper operation.
Table 2-2. Jumper Settings
Jumper Setting Function
JP1 * 1-2,3-4 COM2: TX=Pin3, RX=Pin2 (see silk screen on bottom of
board)
1-3,2-4 COM2: TX=Pin2, RX=Pin3 (see silk screen on bottom of
board)
JP2 Determines the display power pin polarity on the
LCD_PORT. See the schematic
JP3 *1-2 (closest to
RS232
connectors) BDM being used runs at 3.3 volts. So the signals need to go
through a level shifter to get 2.6 volts to the part.
2-3 BDM being used runs at 2.6 volts.
BRK_EN *inserted SWITCH1 will act as a debounced Non-Maskable Interrupt
(ABORT)
