type

discussed in a following paragraph For 64/68 pin packages,

individual channel TX status can be read by examining

individual internal registers via -CS and A0-A4 pin func-

tions.

This function is associated with 100 pin packages only.

These outputs provide the TX FIFO/THR status for indi-

vidual transmit channels

(A-D). As such, an individual

channel’s -TXRDY A-D buffer ready status is indicated by

logic 0, i.e., at least one location is empty and available in

the FIFO or THR. This pin goes to a logic 1 when there are

no more empty locations in the FIFO or THR.

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 (see figure 8). Alternatively, an external clock can be

connected to this pin to provide custom data rates (see

Baud Rate Generator Programming and optional MIDCLK).

Carrier Detect (active low) - These inputs are associated

with individual UART channels A through D. A logic 0 on this

pin indicates that a carrier has been detected by the modem

for that channel.

I

Clear to Send (active low) - These inputs are associated with

individual UART channels, A through D. A logic 0 on the -

CTS pin indicates the modem or data set is ready to accept

transmit data from the 654. Status can be tested by reading

MSR bit-4. This pin only affects the transmit and receive

operations when Auto CTS function is enabled via the
