Preliminary Specification
This is a preliminary specification and is subject to change.
15. Watchdog Timer
15.5 Interrupts
Watchdog timer interrupts 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 an vector. When using multiple functions, read the detect
flag in an interrupt process program to determine which interrupt factor sends an interrupt request.
The VW2C3 bit in the VW2C register is the detect flag for the watchdog timer. After the interrupt factor is
determined, set the VW2C3 bit to 0 (not detected) by a program.
