(4) Interrupt Mask Register (INT2MSKR)
INT2MSKR is a 32-bit readable/writable register that can mask interrupts for sources indicated in
the interrupt source register. When a bit in this register is set to 1, the interrupt in the
corresponding bit is not notified. INT2MSKR is initialized to H'FFFF FFFF (all masked) by a
reset.
After this register is written to or the masking is cleared by writing to INT2MSKCLR, the timing
required to reflect the register value is guaranteed by reading from this register once.
