External interrupt input
The input circuit type and the interrupt level are set in the mask options.
(Pulled up, pulled down, or open)
(Rising edge or falling edge)
A level hold function, which is designed to prevent input floating states
from occurring, is also available as an option.
Interrupt reception: disabled
Level hold function: operational
INT
Input
4-bit input port
Pull-up and pull-down resistors, which can be enabled or disabled under
program control in a single port unit, are built in.
Input signal transition detection circuits and chattering exclusion circuits,
which can be enabled or disabled under program control in 1-bit units, are
built in.
The chattering exclusion time differs depending on the oscillator
specifications.
When a 32.768 kHz crystal oscillator is used the time will be 1.95 or 7.8 ms.
A level hold function, which is designed to prevent input floating states
from occurring on these pins, is also available as an option.
Pull-down or pull-up resistors: enabled
(After the reset is cleared: disabled)
Level hold function: operation disabled
(After the reset is cleared: operation starts)
