Watchdog Timer Reload Upper, High and Low Byte Registers
Description
WDT Reload Upper Byte
Most-significant byte (MSB); bits[23:16] of the 24-bit WDT reload value.
Description
WDT Reload High Byte
Middle byte; bits[15:8] of the 24-bit WDT reload value.

The Watchdog Timer Reload Upper, High and Low Byte (WDTU, WDTH, WDTL) regis-
ters, shown in Tables 60 through 62, form the 24-bit reload value that is loaded into the
Watchdog Timer when a WDT instruction executes. The 24-bit reload value ranges across
bits [23:0] to encompass the three bytes {WDTU[7:0], WDTH[7:0], WDTL[7:0]}. Writ-
ing to these registers sets the appropriate reload value. Reading from these registers
returns the current Watchdog Timer count value.
The 24-bit WDT reload value must not be set to a value less than
Table 60. Watchdog Timer Reload Upper Byte Register (WDTU)
Table 61. Watchdog Timer Reload High Byte Register (WDTH)
