OP1
(-RTSB)
O
Output 1 (General Purpose Output).
This output can also
be programmed to function as the active-low, “Channel B
Request-to-Send” Output (-RTSB).

OP3
(TXCB_1X)
(RXCB_1X)
(-C/T_RDY)
O
Output 3 (General Purpose Output).
This output port can
also be programmed to function as: the “Channel B Trans-
mitter 1X clock” output (TXCB_1X), the “Channel B Receiv-
er 1X clock” output (RXCB_1X), or the open drain, active-
low “Counter/Timer Ready” output (-C/T_RDY).

OP5
(-RXRDY/
-FFULL_B)
O
Output 5 (General Purpose Output Pin).
This output port
pin can also be programmed to function as the open-drain,
active-low, Channel B “Receive Ready” or “Receiver FIFO
Full” indicator output (-RXRDY_B/-FFULL_B).

OP7
(TXRDY_B)
O
Output 7. (General Purpose Output Pin).
This output port
pin can also be programmed to function as the open-drain,
active-low, “Transmitter Ready” indicator output for Channel
B (-TXRDY_B).

D7
I/O
MSB of the Eight Bit Bi-Directional Data Bus.
All transfers
between the CPU and the DUART take place over this bus
(consisting of pins D0 - D7). The bus is tri-stated when the
-
CS input is “high”, except during an IACK cycle (in the Z-
Mode).

-
INTR
O
Interrupt Request Output (Active Low, Open Drain).
-
INTR is asserted upon the occurrence of one or more of the
chip’s maskable interrupting conditions. This signal will re-
main asserted throughout the Interrupt Service Routine and
will be negated once the condition(s) causing the Interrupt
Request has been eliminated.

OP6
(-TXRDY_A)
O
Output 6 (General Purpose Output).
This output pin can
also be programmed to function as the open drain, active-
