The tables in this chapter describe EVB connector signals.

4.2 CONNECTOR SIGNAL DESCRIPTIONS

The following are all the connectors on the board include pin number mnemonic and signal
description.
Connector P7 connects external power to the EVB. the host computer connects to the EVB via
P4. POD1 through POD7 let you connect a logic analyzer to the EVB. P2 and P3 are EVB I/O
ports for evaluating RS-232C devices.
The signal descriptions in the following tables are for quick
reference only. For a complete description of the MCU signals
consult the appropriate MCU user's manual, data book, or technical
summary. For a complete description of the SCSI signals consult
