Request to Send (Active-LOW). These outputs are associated with individual
UART channels, A through B. A logic 0 on the RTS pin indicates the transmitter
has data ready and waiting to send. Writing a logic 1 in the modem control register
MCR[1] will set this pin to a logic 0, indicating data is available. After a reset this
pin will be set to a logic 1. This pin has no effect on the UART’s transmit or receive
operation.
Receive data A, B. These inputs are associated with individual serial channel
data to the SC16C652B receive input circuits, A-B. The RX signal will be a logic 1
during reset, idle (no data), or when the transmitter is disabled. During the local
loop-back mode, the RX input pin is disabled and TX data is connected to the
UART RX input, internally.
Transmit data A, B. These outputs are associated with individual serial transmit
channel data from the SC16C652B. The TX signal will be a logic 1 during reset,
idle (no data), or when the transmitter is disabled. During the local loop-back
mode, the TX output pin is disabled and TX data is internally connected to the
UART RX input.
