Name and Function
Command/data: Input pin indicating data
access or command access.
Gate A
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 P1
P2
matrix. The number of keys can be further
increased by use of other output ports.)
Host interface data bus: 8-bit bidirectional
bus by which a host processor accesses the
host interface.
Host chip select 2: Input pin for selecting
host interface channel 2.
I/O write: Write strobe input pin for the host
interface.
Analog input: Analog signal input pins for
the A/D converter.
A/D trigger: External trigger input for
starting the A/D converter.
Analog output: Analog signal output pins
for the D/A converter.
Analog reference voltage: Reference
voltage pin for the A/D and D/A converters.
If the A/D and D/A converters are not used,
connect AV
Analog ground: Ground pin for the A/D and
D/A converters. Connect to system ground
(0 V).
Analog reference voltage: Analog
reference voltage input pins for A/D and D/A
converters.
