O
Gate A₂₀: A₂₀ gate control signal output pin.
O Host interrupts 1, 11, and 12: Output pins
for interrupt request signals to the host
processor.
I
Keyboard input: Input pins from a matrix
keyboard. (Keyboard scan signals are
normally output from P1₀ to P1₇ and P2₀ to
P2₇, allowing a maximum 16 × 16 key
matrix. The number of keys can be further
increased by use of other output ports.)
