INTERRUPT SUB MASK (INTSUBMSK) REGISTER
This register has 27 bits each of which is related to an interrupt source. If a specific bit is set to 1, the interrupt
request from the corresponding interrupt source is not serviced by the CPU (note that even in such a case, the
corresponding bit of the SUBSRCPND register is set to 1). If the mask bit is 0, the interrupt request can be
serviced.
