types except the 28 pin ST16C1551. The crystal oscillator
output or buffered clock output should be left open if an
external clock is connected to XTAL1.

I
Carrier Detect (active low) - A logic 0 on this pin indicates
that a carrier has been detected by the modem.
-CTS

I
Clear to Send (active low) - A logic 0 on the -CTS pin
indicates the modem or data set is ready to accept transmit
data from the 155X. Status can be tested by reading MSR
bit-4. This pin has no effect on the UARTs transmit or
receive operation.
-DSR

I
Data Set Ready (active low) - A logic 0 on this pin 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
UARTs transmit or receive operation.
-DTR

O
Data Terminal Ready (active low) - A logic 0 on this pin
indicates that the 155X is powered-on and ready. This pin
can be controlled via the modem control register. 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 UARTs transmit or receive operation.
-RI

I
Ring Indicator (active low) - A logic 0 on this pin indicates the
modem has received a ringing signal from the telephone
line. A logic 1 transition on this input pin will generate an
interrupt.
-RTS

31
O
Request to Send (active low) - 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 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 has no effect
on the UARTs transmit or receive operation.
