MASK
For the MASK register following logical states are applied:
0: Interrupt is not masked
1: Interrupt is masked
Each interrupt source in the ISTA register can be selectively masked by setting to ’1’ the
corresponding bit in MASK. Masked interrupt status bits are not indicated when ISTA is
read. Instead, they remain internally stored and pending, until the mask bit is reset to ’0’.
Note: In the event of a C/I channel change, CIC is set in ISTA even if the corresponding
