Pin No. Signal Name Attribute Description
A1 SCC1RXD (PD31
a
) I/O, T.S. When RS232 port #1 is enabled, this signal is the receive data
line for SCC1 port. When this port is disabled, this signal is
tristated and may be used to any available alternate function for
PD31.
A2 SCC1RXD (PD30) I/O, T.S. When RS232 port #1 is enabled, this signal is the transmit data
line for SCC1 port. When this port is disabled, this signal may be
used to any available alternate function for PD30.
A3 SCC1CTSb (PD29) I/O, T.S When RS232 port #1 is enabled, this signal is the carrier detect
line for SCC1 port. When this port is disabled, this signal may be
used to any available alternate function for PD29.
