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 16C450 to CPU during a
read operation.

Chip Select-0. Logical 1 on this pin provides the chip select-

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
ST16C450 during a write operation.
-AS
25
28
24
I
Address Strobe. A logic 0 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 (it is edge triggered).

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.
