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

Note 1
The default priority determines the sequence of interrupts if two or more maskable interrupts occur
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.
simultaneously. Zero indicates the highest priority.
