rupt or Cascade mode.

SETTING DESCRIPTION
Timer Only Use this setting to specify that the Watchdog is to be operated in Timer Only mode.
Reset Use this setting to specify that the Watchdog is to reset the system if it is not retriggered
within the selected time.
Interrupt Use this setting to specify that the Watchdog is to generate an interrupt if it is not retriggered
within the selected time.
Cascade
(Interrupt + Reset) Use this setting to specify that the Watchdog is to be operated in Cascade mode.
In this mode, if the Watchdog is not retriggered within the selected time, an interrupt is gen-
erated and the Watchdog is automatically retriggered. If the Watchdog subsequently times
out again, the system will be reset.
If the Watchdog is retriggered normally after the interrupt, the next timeout will result in the
generation of an interrupt and the automatic retriggering of the Watchdog.
SETTING DESCRIPTION
Disabled Use this setting to disable this function.
IRQ5 Use this setting to specify that the Watchdog is to generate an IRQ5 interrupt when operated
in Interrupt or Cascade mode.
NMI Use this setting to specify that the Watchdog is to generate a Non-Maskable Interrupt (NMI)
when operated in Interrupt or Cascade mode.
