INT0 to
INT6
Can be used as interrupt request inputs ch0 to ch6.
In standby mode, these pins can operate as inputs
by setting the bits corresponding to EN0 to EN6 to
“1” and setting as input ports. When used as a port,
set the corresponding bits in the analog input
enable register (ADER) to “port”.

FRCK
External clock input pin for the freerun timer.
This pin can be used as an input when set as the
clock input for the freerun timer and set as an input
port. When used as a port, set the corresponding
bit in the analog input enable register (ADER) to
“port”.
