To clear each interrupt mask, write 1 to the corresponding bit of the INTMSKCLR00 register. The
values in INTMSK00 do not change if you write 0 to it.
Bits 31 to 0—Interrupt Masks: These bits indicate the existence of an interrupt request
corresponding to each bit. For the correspondence between bits and interrupt sources, see section
19.3.7, INTREQ00, INTMSK00, and INTMSKCLR00 Bit Allocation.
