Name and Function
Host interface data bus: Bidirectional 8-bit bus for
accessing the host interface.
Chip select 1, 2, 3, and 4: Input pins for selecting
host interface channel 1 to 4.
I/O read: Input pin that enables reading from the
host interface.
I/O write: Input pin that enables writing to the host
interface.
Command/data: Input pin that indicates whether
an access is a data access or command access.
interrupt requests to the host.
Host interface shutdown: Control input pin used
to place host interface input/output pins in the high-
impedance/cutoff state.
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
Analog input: A/D converter analog input pins.
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.
A/D conversion external trigger input: Pin for
input of an external trigger to start A/D conversion.
16-input, 256-key matrix to be configured.
