Table 28-1 lists the memory-mapped registers for the WDT. All register offset addresses not listed in Table 28-1 should be considered as reserved locations and the register contents should not be modified.
The offset is relative to the Watchdog Timer base address:
The Watchdog Timer module clock must be enabled before the registers can be programmed (see Section 4.2.85).
