Address data lines [2:0]. These 3 address lines select one
of the internal registers in UART channel A/B during a
data bus transaction.

IO
Data bus lines [7:0] (bidirectional).
IOR#

24
19
I
Input/Output Read Strobe (active low). The falling edge
instigates an internal read cycle and retrieves the data
byte from an internal register pointed to by the address
lines [A2:A0]. The data byte is placed on the data bus to
allow the host processor to read it on the rising edge.
IOW#
18
20
15
I
Input/Output Write Strobe (active low). The falling edge
instigates an internal write cycle and the rising edge
transfers the data byte on the data bus to an internal reg-
ister pointed by the address lines.
CSA#
14

I
UART channel A select (active low) to enable UART
channel A in the device for data bus operation.
CSB#

I
UART channel B select (active low) to enable UART
channel B in the device for data bus operation.
INTA

30
O
UART channel A Interrupt output. The output state is
defined by the user and through the software setting of
MCR[3]. INTA is set to the active mode and OP2A# out-
put to a logic 0 when MCR[3] is set to a logic 1. INTA is
set to the three state mode and OP2A# to a logic 1 when
MCR[3] is set to a logic 0 (default). See MCR[3].
INTB

O
UART channel B Interrupt output. The output state is
defined by the user and through the software setting of
MCR[3]. INTB is set to the active mode and OP2B# out-
put to a logic 0 when MCR[3] is set to a logic 1. INTB is
set to the three state mode and OP2B# to a logic 1 when
MCR[3] is set to a logic 0 (default). See MCR[3].
TXRDYA#

43
O
UART channel A Transmitter Ready (active low). The out-
put provides the TX FIFO/THR status for transmit channel
A. See Table 2. If it is not used, leave it unconnected.
RXRDYA#
-
34
31
O
UART channel A Receiver Ready (active low). This out-
put provides the RX FIFO/RHR status for receive channel
A. See Table 2. If it is not used, leave it unconnected.
