INTMSK0 is 32-bit readable and writable with conditions registers that control mask settings for
each interrupt request. To clear the mask settings for interrupts, write 1 to the corresponding bits
in INTMSKCLR0. Writing 0 to bits in INTMSK0 is invalid.
Note: Write B'1111 to the IM [03:00] or IM [07:04] bits when IRQ3/IRL3 to IRQ0/IRL0 or
