• IOCON0 controls the functionality of the
The IARES (Interrupt Activity Resolution) bit controls
the sampling frequency of the GP port pins. The higher
the sampling frequency, the higher the device current
requirements. If this bit is ‘0’ (default), the maximum
time to detect the activity on the port is 32 ms (max.),
which results in lower standby current. If this bit is ‘1’,
the maximum time to detect activity on the port is
200 µsec. (max.) and results in higher standby current.

IOCON1 is a shadow register for IOCON0. Access to IOCON1 results in access to IOCON0.
