I
Read data strobe. Its function is the same as -IOR (see -
IOR), except it is active high. Either an active -IOR or IOR
is required to transfer data from 16C550 to CPU during a
read operation. Connect to logic 0 when using -IOR.
CS0

I
Chip Select-0. Logical 1 on this pin provides the chip select-
0 function. Connect CS0 to logic 1 if using CS1 or -CS2.
CS1

I
Chip Select-1. Logical 1 on this pin provides the chip select-

I
Chip Select -2. Logical 0 on this pin provides the chip select-
2 function. Connect to logic 0 if using CS0 or CS1.
IOW

I
Write data strobe. Its function is the same as -IOW (see -
IOW), but it acts as an active high input signal. Either -IOW
or IOW is required to transfer data from the CPU to
ST16C550 during a write operation. Connect to logic 0 when
using -IOW.
-AS
25
28
24
I
Address Strobe. A logic 1 transition on -AS latches the state
of the chip selects and the register select bits, A0-A2. This
input is used when address and chip selects are not stable
for the duration of a read or write operation, i.e., a micropro-
cessor that needs to de-multiplex the address and data bits.
If not required, the -AS input can be permanently tied to a
logic 0.

I/O
Data Bus (Bi-directional) - These pins are the eight bit, tri-
state data bus for transferring information to or from the
controlling CPU. D0 is the least significant bit and the first
data bit in a transmit or receive serial data stream.
