The timer RC interrupt, synchronous serial communication unit interrupt, I
memory interrupt each have multiple interrupt request sources. An interrupt request is generated by the logical OR
of several interrupt request sources and is reflected in the IR bit in the corresponding interrupt control register.
Therefore, each of these peripheral functions has its own interrupt request source status register (status register) and
interrupt request source enable register (enable register) to control the generation of interrupt requests (change of
the IR bit in the interrupt control register). Table 11.10 lists the Registers Associated with Timer RC Interrupt,
