12.1.6.9
When the REIT instruction is executed at the end of an interrupt routine, the FLG register and PC, which have
been saved to the stack, are automatically returned. The program, executed before the interrupt request has
been acknowledged, starts running again.
Return the register saved by a program in an interrupt routine using the POPM instruction or others before the
REIT instruction.
If two or more interrupt requests are generated while executing one instruction, the interrupt with the higher
priority is acknowledged.
Set the ILVL2 to ILVL0 bits to select the desired priority level for maskable interrupts (peripheral functions).
However, if two or more maskable interrupts have the same priority level, their interrupt priority is resolved by
hardware, with the higher priority interrupt acknowledged in hardware.
The priority levels of special interrupts such as reset (reset has the highest priority) and watchdog timer are set
by hardware.
Figure 12.10 shows the Priority Levels of Hardware Interrupts.
The interrupt priority does not affect software interrupts. The MCU jumps to the interrupt routine when the
instruction is executed.
