This bit is set to 0 when the read result is 1 and 0 is written to the same bit. This bit remains
unchanged even if the read result is 0 and 0 is written to the same bit. This bit remains unchanged if
1 is written to it.
The DTCTL register controls DTC activation when a non-maskable interrupt (an interrupt by the watchdog
timer, oscillation stop detection, voltage monitor 1, or voltage monitor 2) is generated.
The NMIF bit is set to 1 when a watchdog timer interrupt, an oscillation stop detection interrupt, a voltage
monitor 1 interrupt, or a voltage monitor 2 interrupt is generated.
When the NMIF bit is 1, the DTC is not activated even if the interrupt which enables DTC activation is
generated. If the NMIF bit is changed to 1 during DTC transfer, the transfer is continued until it is completed.
When an interrupt source is the watchdog timer, wait for the following cycles before writing 0 to the NMIF bit:
If the WDTC7 bit in the WDTC register is set to 0 (divide-by-16 using the prescaler), wait for 16 cycles of the
CPU clock after the interrupt source is generated.
If the WDTC7 bit is set to 1 (divide-by-128 using the prescaler), wait for 128 cycles of the CPU clock after the
interrupt source is generated.
When an interrupt source is oscillation stop detection, set to the OCD1 bit in the OCD register to 0 (oscillation
stop detection interrupt disabled) before writing 0 to the NMIF bit.
