Each interrupt source can be selectively masked by setting the respective bit in the
MASK_A/B-register (bit position corresponding to the ISTA_A/B-register). Masked
interrupts are internally stored but not indicated when reading ISTA_A/B and also not
flagged into the top level ISTA. After releasing the respective MASK_A/B-bit they will be
indicated again in ISTA_A/B and in the top level ISTA.
When writing register MASK_A/B while ISTA_A/B indicates a non masked interrupt the
INT-pin is temporarily set into the inactive state. In this case the interrupt remains
indicated in the ISTA_A/B until these registers are read.
