07 : 00 FFh RW PLOAD2_7_0
Preload_Value_2 [7:0]: This register is used to hold the bits 0 through
7 of the preload value 2 for the WDT Timer. The Value in the Preload
Register is automatically transferred into the 35-bit down counter.
The value loaded into the preload register needs to be one less than the
intended period. This is because the timer makes use of zero-based
counting (i.e., zero is counted as part of the decrement).
Refer to Section 11.10.4.2 for details on how to change the value of this
register.

07 : 00 FFh RW PLOAD2_15_8
Preload_Value_2 [15:8]: This register is used to hold the bits 8
through 15 of the preload value 2 for the WDT Timer. The Value in the
Preload Register is automatically transferred into the 35-bit down
counter.
The value loaded into the preload register needs to be one less than the
intended period. This is because the timer makes use of zero-based
counting (i.e., zero is counted as part of the decrement).

register.
