(4) INTERRUPT FUNCTIONS
The following two types of interrupt functions are used.
<1> Maskable interrupts
These interrupts undergo mask control.
<2> Software interrupt
This is a vectored interrupt generated by executing the BRK instruction.
The following maskable interrupts are available.

3.
The default priority determines the sequence of interrupts if two or more maskable interrupts occur
simultaneously. Zero indicates the highest priority.
When bit 7 (WDTINT) of the option byte (00C0H) is set to 1.
When bit 1 (LVIMD) of the low-voltage detection register (LVIM) is cleared to 0.
