Watchdog Lock (WDTLOCK)
Writing 0x1ACCE551 to the WDTLOCK register enables write access to all other registers. Writing any other value to the WDTLOCK register re-enables the locked state for register writes to all the other registers, except for the Watchdog Test (WDTTEST) register. Reading the WDTLOCK register returns the lock status rather than the 32-bit value written. Therefore, when write accesses are disabled, reading the WDTLOCK register returns 0x00000001 when locked; otherwise, the returned value is 0x00000000 when unlocked.
WDTLOCK is shown in Figure 28-9 and described in Table 28-10.
