Watchdog Timer Reload Unlock Sequence
Watchdog Timer Reload High and Low Byte Registers
WDT Reset in Normal Operation
If configured to generate a Reset when a timeout occurs, the WDT forces the device into
the Reset state. The WDT status bit in the
more information about Reset and the WDT status bit, see the the
Recovery
with its reset value.
WDT Reset in STOP Mode
If enabled in STOP mode and configured to generate a Reset when a timeout occurs and
the device is in STOP mode, the WDT initiates a Stop Mode Recovery. Both the WDT
status bit and the STOP bit in the
WDT timeout in STOP mode. For detailed information, see the
Recovery
Writing the unlock sequence to the Watchdog Timer Reload High (WDTH) register
address unlocks the two Watchdog Timer Reload registers (WDTH and WDTL) to allow
changes to the timeout period. These Write operations to the WDTH Register address pro-
duce no effect on the bits in the WDTH Register. The locking mechanism prevents spuri-
ous writes to the reload registers.
The following sequence is required to unlock the Watchdog Timer Reload registers
(WDTH and WDTL) for write access:
1. Write
2. Write
3. Write the appropriate value to the Watchdog Timer reload high register (WDTH).
4. Write the appropriate value to the Watchdog Timer reload low register (WDTL).
All steps of the WDT reload unlock sequence must be written in the order just listed. The
value in the Watchdog Timer Reload registers is loaded into the counter every time a
instruction is executed.
The Watchdog Timer reload high and low byte (WDTH, WDTL) registers (see Tables 69
and 70) form the 16-bit reload value that is loaded into the WDT when a
executes. The 16-bit reload value is {WDTH[7:0], WDTL[7:0]}. Writing to these registers
