I
FIFO Status Register Select (active low input with internal pull-up).
The content of the FSTAT register is placed on the data bus when
this pin becomes active. However it should be noted, D0-D3 contain
the inverted logic states of TXRDY# A-D pins, and D4-D7 the logic
states (un-inverted) of RXRDY# A-D pins. A valid address is not
required when reading this status register.

O
UART channels A-D Transmit Data and infrared transmit data.
Standard transmit and receive interface is enabled when MCR[6] =
0. In this mode, the TX signal will be a logic 1 during reset, or idle
(no data). Infrared IrDA transmit and receive interface is enabled
when MCR[6] = 1. In the Infrared mode, the inactive state (no data)
for the Infrared encoder/decoder interface is a logic 0.

Regardless of the logic state of MCR bit-6, this pin will be operating
in the Infrared mode.
