Watchdog timer (not recommended)
On some units, you can program a watchdog to perform a system
restart when a programmable timeout occurs. The timeout interval can
with one-second resolution, or from
with one-minute resolution. When the timeout expires, an IRQ15 interrupt
is asserted. With the Reboot upon expiration of watchdog parameter,
you can specify that the system restart at this time. At most, one
block of this type can be included in a model.

Select this check box to restart the unit when the watchdog timer expires. When the timeout expires, an IRQ15 interrupt is asserted, regardless of the state of this check box. If you choose not to restart the system when the watchdog timer expires, you might want to write your own procedure to handle the IRQ15 assertion.
