Input

Matrix keyboard input pins.

.,13 to .,148

are used as key-scan inputs, and P10 to

P17 and P20 to P27 are used as key-scan

outputs. This allows a maximum 16-output

× 16-input, 256-key matrix to be configured.

Input

A/D conversion input pins, but since they

are also used as digital input/output pins,

accuracy will fall.
