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.
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.
UART channel A-D Infrared Transmit Data. 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.
UART channel A-D Receive Data or infrared receive data. Normal
receive data input must idle at logic 1 condition.
UART channels A-D Request-to-Send (active low) or general pur-
pose output. This output must be asserted prior to using auto RTS
flow control, see EFR[6], MCR[1], and IER[6]. Also see
If these outputs are not used, leave them unconnected.
UART channels A-D Clear-to-Send (active low) or general purpose
input. It can be used for auto CTS flow control, see EFR[7], and
IER[7]. Also see
VCC when not used.
UART channels A-D Data-Terminal-Ready (active low) or general
purpose output. If these outputs are not used, leave them uncon-
nected.
UART channels A-D Data-Set-Ready (active low) or general pur-
pose input. This input should be connected to VCC when not used.
This input has no effect on the UART.
UART channels A-D Carrier-Detect (active low) or general purpose
input. This input should be connected to VCC when not used. This
input has no effect on the UART.
