I
Read strobe (active low strobe). A logic 0 on this pin transfers
the contents of the 580 data bus to the CPU.
-IOW
18
20
16
I
Write strobe (active low strobe) - A logic 0 on this pin
transfers the contents of the CPU data bus to the addressed
internal register.
INT
30
33
30
O
Interrupt Request.
-RXRDY
29
32
29
O
Receive Ready. A logic 0 indicates receive data ready
status, i.e. the RHR is full or the FIFO has one or more RX
characters available for unloading. This pin goes to a logic
0 when the FIFO/RHR is full or when there are more
characters available in either the FIFO or RHR.
-TXRDY
24
27
23
O
Transmit Ready. Buffer ready status is indicated by a 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.
-BAUDOUT
15
17
12
O
Baud Rate Generator Output. This pin provides the 16X
clock of the selected data rate from the baud rate generator.
The RCLK pin must be connected externally to -BAUDOUT
when the receiver is operating at the same data rate.
-DDIS
23
26
22
O
Drive Disable. This pin goes to a logic 0 when the external
CPU is reading data from the 580. This signal can be used
to disable external transceivers or other logic functions.
-OP1

34
O
Output-1 (User Defined) - See bit-2 of modem control
register (MCR bit-2).
-OP2
31
35
31
O
Output-2 (User Defined). This pin provides the user a
general purpose output. See bit-3 modem control register
(MCR bit-3).
RCLK
9
10
5
I
Receive Clock Input. This pin is used as external 16X clock
input to the receiver section. External connection to -
Baudout pin is required in order to utilize the internal baud
rate generator.
