Operation when malfunction (runaway) is detected
interrupt (NMI). Thus CPU detects non-maskable interrupt and performs the countermeasure program.
In the case of INTWDT interrupt, CGNMIFLG<NMIFLG0> is set.
WDTOUT becomes "High" by the watchdog timer clearing that is writing clear code 0x4E to the WDCR register.
In the Figure 13-2 shows the case that INTWDT interrupt generates (WDMOD<RESCR>="0").
When an overflow of the binary counter occurs, INTWDT interrupt generates. It is a factor of non-maskable
The factor of non-maskable interrupt is the plural. CGNMIFLG identifies the factor of non-maskable interrupts.
When INTWDT interrupt generates, simultaneously the watchdog timer out (WDTOUT) output "Low".

Note:This product does not have the watchdog timer output pin(WDTOUT).
