Symbol
Pin
Signal Type
Pin Description
-RI A/B
30,6
I
Ring Indicator (active low) - These inputs are associated
with individual UART channels, A through B. A logic 0 on
this pin(s) indicates the modem has received a ringing
signal from the telephone line(s). A logic 1 transition on this
input pin will generate an interrupt for the ringing channel(s).
This pin does not have any effect on the transmit or receive
operation.
-RTS A/B
24,12
O
Request to Send (active low) - These outputs are associated
with individual UART channels, A through B. A logic 0 on the
-RTS pin(s) indicates the transmitter has data ready and
waiting to send for the given channel(s). Writing a logic 1 in
the modem control register (MCR bit-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 does not have any effect on the
transmit or receive operation.
RX A/B
41,62
I
Receive Data Input, RX A-B. - These inputs are associated
with individual serial channel(s) to the 452. 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 pins are disabled and TX data is internally
connected to the UART RX Inputs, internally.
TX A/B
26,10
O
Transmit Data, TX A-B - These outputs are associated with
individual serial transmit channel(s) from the 452/452PS.
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 pins are disabled and TX data is
internally connected to the UART RX Inputs.
