O
UART channel B Transmitter Ready (active low). The out-
put provides the TX FIFO/THR status for transmit channel
B. See Table 2. If it is not used, leave it unconnected.

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

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.

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.

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 out-
put functionality. If it is not used at all, leave it uncon-
nected.
