O
UART channel B Receiver Ready (active low). This output provides
the RX FIFO/RHR status for receive channel B. See Table 2. If it is
not used, leave it unconnected.

I
UART channel A Receive Data. Normal receive data input must idle
at logic 1 condition. If it is not used, tie it to VCC or pull it high via a
100k ohm resistor.

UART channel A Request-to-Send (active low) or general purpose
output. If it is not used, leave it unconnected.

I
UART channel A Clear-to-Send (active low) or general purpose
input. This input should be connected to VCC when not used. This
input has no effect on the UART.

UART channel A Data-Terminal-Ready (active low) or general pur-
pose output. If it is not used, leave it unconnected.

O
Output Port 2 Channel A - The output state is defined by the user
and through the software setting of MCR[3]. INTA is set to the active
mode and OP2A# output to a logic 0 when MCR[3] is set to a logic
1. INTA is set to the three state mode and OP2A# to a logic 1 when
MCR[3] is set to a logic 0. See MCR[3]. This output should not be
used as a general output else it will disturb the INTA output function-
ality. If it is not used at all, leave it unconnected.
