RELOAD Reload. This field is written with a value that will be used
to reload the timer. The RELOAD field may only be
modified on the second step of a successful two step
arming process.
Note An R206 resistor must be installed if a board reset is the result of
a timeout of Watchdog Timer 2. See the attached sample for an
example of PPCBug setting WDT2.
