H0 Interrupt
in RUN mode. H0 interrupt flag H0IF is set in run mode by a
state change of the H0 flag (rising or falling edge on the
enabled input). The interrupt function is available if the input
is selected as General Purpose or as 2pin Hallsensor input.
The interrupt can be masked with the H0IE bit in the interrupt
mask register.

of the input is stored. If the state is changing during in the
STOP or SLEEP mode a wake-up is initiated.
