11.8 INTERNAL INTERRUPT (TIMER, SERIAL INTERFACE)
There are two types of internal interrupts: the timer interrupt and the serial interface interrupt.
11.8.1 Timer Interrupt
The timer interrupt function can issue interrupt requests at a specified time interval.
An interval of 100 ms, 20 ms, or 5 ms can be selected.
See Chapter 12 for details.
11.8.2 Serial Interface Interrupt
The serial interface interrupt function can issue an interrupt request when a serial out or serial in operation
terminates.
Therefore, interrupt requests are mainly issued by the serial clock.
See Chapter 16 for details.
