Pin Description
effect on the transmit or receive operation.
-DSR A/B
31,5
I
Data Set Ready (active low) - These inputs are associated
with individual UART channels, A through B. A logic 0 on
this pin(s) indicates the modem or data set is powered-on
and is ready for data exchange with the UART. This pin has
no effect on the UART’s transmit or receive operation.
-DTR A/B
25,11
O
Data Terminal Ready (active low) - These outputs are
associated with individual UART channels, A through B. A
logic 0 on this pin(s) indicates that the 552/552A is powered-
on and ready. This pin can be controlled via the modem
control register for channel(s) A-B. Writing a logic 1 to MCR
bit-0 will set the -DTR output to logic 0, enabling the modem.
This pin will be a logic 1 after writing a logic 0 to MCR bit-
0, or after a reset. This pin has no effect on the UART’s
transmit or receive operation.
-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 552. 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
