Name and Function
Host interface data bus: 8-bit
bidirectional bus by which a host
processor accesses the host interface.
Chip select 1 and 2: Input pins for
selecting host interface channels 1 and
2.
I/O read: Read strobe input pin for the
host interface.
I/O write: Write strobe input pin for the
host interface.
Command/data: Input pin indicating
data access or command access.
Gate A₂₀: A₂₀ gate control signal output
pin.
Host interrupts 1, 11, and 12: Output
pins for interrupt request signals to the
host processor.
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 × 8 key matrix. The
number of keys can be further
increased by use of other output
ports.)
Host chip select 2: Input pin for
selecting host interface channel 2.
I/O write: Write strobe input pin for the
host interface.
