Interrupt Mask Registers
A ‘0’ in a bit position masks the corresponding interrupt (default value, i.e. after Reset).
The mask bit affects only the generation of the interrupt, but not the interrupt status bit
from being set.
Acknowledge Register
The interrupt status bit is reset when the host writes a ‘1’ in the corresponding bit
position.
The other interrupt status bits are reset when the input/output registers are read or
written:
