As with other maskable interrupts, the timer RD (channel 0) interrupt, timer RD (channel 1) interrupt, clock
synchronous serial I/O with chip select interrupt, and I
of the I flag, IR bit, bits ILVL0 to ILVL2, and IPL. However, since each interrupt source is generated by a
combination of multiple interrupt request sources, the following differences from other maskable interrupts apply:
Refer to chapters of the individual peripheral functions (14.3 Timer RD, 16.2 Clock Synchronous Serial I/O with
Chip Select (SSU) and 16.3 I
Refer to 12.1.6 Interrupt Control for the interrupt control register.

both, are set to 0, the IR bit is set to 0 (interrupt not requested). Basically, even though the interrupt is not
acknowledged after the IR bit is set to 1, the interrupt request will not be maintained. Also, the IR bit is not set
to 0 even if 0 is written to the IR bit.
Therefore, the IR bit is also not automatically set to 0 when the interrupt is acknowledged. Set each bit in the
status register to 0 in the interrupt routine. Refer to the status register figure for how to set individual bits in the
status register to 0.
