Input Chip select 1, 2, 3, and 4: Input pins for selecting
host interface channel 1 to 4.
IOR 22 Input I/O read: Input pin that enables reading from the
host interface.
IOW 19 Input I/O write: Input pin that enables writing to the host
interface.
HA0 93 Input Command/data: Input pin that indicates whether
an access is a data access or command access.
GA20 94 Output GATE A20: A20 gate control signal output pin.

Output Host interrupt 11, 1, 12, 3, and 4: Output pins for
interrupt requests to the host.
HIFSD 95 Input Host interface shutdown: Control input pin used
to place host interface input/output pins in the high-
impedance/cutoff state.

Input Keyboard input: Matrix keyboard input pins.
Normally, P10 to P17 and P20 to P27 are used as
key-scan outputs. This enables a maximum 16-
output × 16-input, 256-key matrix to be configured.

Input Expansion A/D inputs: Expansion A/D input pins
can be connected to the A/D converter, but since
they are also used as digital input/output pins,
precision will fall.
ADTRG 25 Input A/D conversion external trigger input: Pin for
input of an external trigger to start A/D conversion.
