7.2.1 Watchdog load register (WDT_LR)
The WDT_LR register is a 32-bit register containing the value from which the counter is to
decrement. When this register is written to, the count is immediately re-started from the new
value.
The minimum valid value for WDT_LR is 0x1.
Table 27. Watchdog load register WDT_LR
7.2.2 Watchdog value register WDT_VAL
The WDT_VAL register gives the current value of the decrementing watchdog counter.
