instruction executes. The 16-bit reload value is {WDTH[7:0], WDTL[7:0]}. Writing to
these registers following the unlock sequence sets the appropriate reload value. Reading
from these registers returns the current WDT count value.
The 16-bit WDT Reload Value must not be set to a value less than

WDTH—WDT reload high byte
Most significant byte (MSB), Bits[15:8], of the 16-bit WDT reload value.
7
WDTL—WDT reload low
Least significant byte (LSB), Bits[7:0], of the 16-bit WDT reload value.
