SYMBOL DESCRIPTION
XTAL2
13
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
42,30
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
40,28
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 2552. Status
can be tested by reading MSR bit-4. This pin has no effect on the UARTs
transmit or receive operation.
-DSR A-B
41,29
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
37,27
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 2552 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 A-B
43,31
I
Ring Indicator (active low) - These inputs are associated with individual
UART channels, A through B. 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 A-B
36,23
O
Request to Send (active low) - These outputs are associated with
individual UART channels, A through B. 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.
RX A-B
39,25
I
Receive Data (A-B) - These inputs are associated with individual serial
channel data to the 2552 receive input circuits, A-B. The RX signal will be
a logic 1 during reset, idle (no data), or when the transmitter is disabled.
