Each interrupt source/group can be selectively masked by setting the respective bit in
the MASK-register (bit position corresponding to the ISTA-register). A masked IDA-
interrupt is not indicated when reading ISTA. Instead it remains internally stored and will
be indicated after the respective MASK-bit is reset. The watchdog timer interrupts is not
maskable.
Even with a set MASK-bit EPIC-1 and SACCO-interrupts are indicated but no interrupt
signal is generated.
When writing the MASK-register while an interrupt is indicated, INT is temporarily set into
the inactive state.
