The timer RC interrupt, clock synchronous serial I/O with chip select interrupt, and I
have multiple interrupt request sources. An interrupt request is generated by the logical OR of several interrupt
request factors 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 the IR bit in the interrupt
control register). Table 12.9 lists the Registers Associated with Timer RC Interrupt, Clock Synchronous Serial I/O
with Chip Select Interrupt, and I
Interrupt.
