Preliminary Specification
This is a preliminary specification and is subject to change.
7. Voltage Detector
7.5 Interrupts
The voltage monitor 1 interrupt and voltage monitor 2 interrupt are non-maskable interrupts.
The watchdog timer interrupt, oscillation stop and re-oscillation detection interrupt, voltage monitor 1
interrupt, and voltage monitor 2 interrupt share the same interrupt vector. When using some functions
together, read the detect flags of the events in an interrupt processing program, and determine the
interrupt source of the interrupt request.
The detect flag for voltage monitor 1 is the VW1C2 bit in the VW1C register, and the detect flag for voltage
monitor 2 is the VW2C2 bit in the VW2C register. After the interrupt source is determined, set bits VW1C2
and VW2C2 to 0 (not detected).
