When the REIT instruction is executed at the end of an interrupt routine, the FLG register and PC, which have
been saved on the stack, are automatically restored. The program, that was running before the interrupt request
was acknowledged, starts running again.
Registers saved by a program in an interrupt routine should be saved using the POPM instruction or a similar
instruction before executing the REIT instruction.
If two or more interrupt requests are generated while a single instruction is being executed, the interrupt with
the higher priority is acknowledged.
Set bits ILVL2 to ILVL0 to select any priority level for maskable interrupts (peripheral function). However, if
two or more maskable interrupts have the same priority level, their interrupt priority is resolved by hardware,
with the higher priority interrupts acknowledged.
The priority of the watchdog timer and other special interrupts is set by hardware.
Figure 11.7 shows the Hardware Interrupt Priority.
Software interrupts are not affected by the interrupt priority. When an instruction is executed, the MCU
executes the interrupt routine.
