used as digital I/Os or analog inputs.
P130 functions as a 1-bit output port.
Remark When the device is reset, P130 outputs a low level. Therefore, to output a high level from P130 before
P140 and P141 function as a 2-bit I/O port. These pins also function as external interrupt request input and
The following operation modes can be specified in 1-bit units.
This is the A/D converter reference voltage input pin and the positive power supply pin of P20 to P27, and A/D
The voltage that can be supplied to AV
P140 and P141 function as a 2-bit I/O port. P140 and P141 can be set to input or output port in 1-bit units using
port mode register 14 (PM14). Use of an on-chip pull-up resistor can be specified by pull-up resistor option
register 14 (PU14).
P140 and P141 function as external interrupt request input, and clock/buzzer output.

Using at least one pin as an analog input and using all
pins not as digital I/Os
Pins used as analog inputs and digital I/Os are
mixed
Using at least one pin as a digital I/O and using all pins
not as analog inputs
These are the external interrupt request input pins for which the valid edge (rising edge, falling edge, or both
rising and falling edges) can be specified.
These are the clock/buzzer output pins.
