Pin Description
with a printer to select the printer with an active low.
-STROBE
55
I/O
Strobe (open drain, with internal pull-up) - General purpose
I/O or data strobe output. Normally this output is connected
to a printer and indicates that valid data is available at the
printer port (PD0-PD7).
N.C.
22,42
Not Used. Should be left open.
VCC
23,40,64
Pwr
2.97 to 5.5V power supply input. All inputs are 5V tolerant
except for XTAL1 and all printer port inputs for devices with top
mark date code of "F2 YYWW" and newer.
-CD A/B
29,8
I
Carrier Detect (active low) - These inputs are associated
with individual UART channels A through B. A logic 0 on this
pin indicates that a carrier has been detected by the modem
for that channel.
-CTS A/B
28,13
I
Clear to Send (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 ready to accept
transmit data from the 452/452PS for the given channel.
Status can be tested by reading MSR bit-4 for that
channel(s). -CTS has no 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 452/452PS 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
