INTMSK2 is a 32-bit readable and conditionally writable register that sets masking for IRL
interrupt requests for input level pattern on the IRL pins. To clear the mask setting for the
interrupt, write 1 to the corresponding bit in INTMSKCLR2. Writing 0 to the bits in INTMSK2
has no effect. By reading this register once after writing to this register or after clearing the mask
by setting IMTMSKCLR2, the time length necessary for reflecting the register value can be
assured (the value read is reflected to the mask status).
INTMSK2 settings are valid when the IRQ/IRL3 to IRQ/IRL0 pins or IRQ/IRL7 to IRQ/IRL4
pins are used for encoded IRL interrupt inputs, and the corresponding IRL interrupt is not masked
by INTMSK1.
