Pin No. Symbol
Pin Name
Function and Operation
4-bit I/O ports, allowing input and output
to be programmed in 1 bit units.
Pins P5-0 to P5-3 can also be used for
analog input to the built-in 6 bit,
4-channel AD converter.

/AD analog voltage
input
The conversion time of the built-in AD
converter using the successive
comparison method is 280 µs. The
necessary pin can be programmed to
AD analog input in 1 bit units. Up to the
doubled voltage VDB (VDD × 2) can be
input as the AD input voltage.
I/O ports are N-ch open drain output.
Up to the VDB voltage can be applied to
the AD input pins.
The AD converter and all associated
controls are performed via sortware.
1 bit output port, normally used for
muting control signal output.
32 MUTE
Muting output port
This pin can set the internal MUTE bit
to “1” according to a change in the input
of I/O port 1 and HOLD . MUTE bit
output logic can be changed.
The internal CR oscillator clock can be
output depending on the contents of the
test port.
33 TEST
Test mode control
input
Input pin used for controlling TEST
mode.
“H” (high) level indicates TEST mode,
while “L” (low) indicates normal
operation.
The pin is normally used at low level or
in NC (no connection) state.
(A pull-down resistor is builtin).
