I
Crystal or External Clock Input - Functions as a crystal input
or as an external clock input. A crystal can be connected
between this pin and XTAL2 to form an internal oscillator
circuit. This configuration requires an external 1 MW resis-
tor between the XTAL1 and XTAL2 pins. Alternatively, an
external clock can be connected to this pin to provide
custom data rates (see Baud Rate Generator Program-
ming).
XTAL2

O
Output of the Crystal Oscillator or Buffered Clock - (See also
XTAL1). Crystal oscillator output or buffered clock output.
Should be left open if an external clock is connected to
XTAL1.
-CD A-B
38,19
42,21
40,16
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
36,25
40,28
38,23
I
Clear to Send (active low) - These inputs are associated with
individual UART channels, A through B. A logic 0 on the -
CTS pin indicates the modem or data set is ready to accept
transmit data from the 2550. Status can be tested by reading
MSR bit-4. This pin has no effect on the UARTs transmit or
receive operation.
-DSR A-B
37,22
41,25
39,20
I
Data Set Ready (active low) - These inputs are associated
with individual UART channels, A through B. 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 A-B
33,34
37,38
34,35
O
Data Terminal Ready (active low) - These outputs are
associated with individual UART channels, A through B. A
logic 0 on this pin indicates that the 2550 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
