A1

SCC1RXD (PD31a)

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.
