WPHS - WDT command status register
The WPHS register monitors the success of a write instruction to the WDTM
and WDCS registers.
If the write operation to WDTM or WDCS failed because WCMD was not
written immediately before writing to WDTM or WDCS, the WPRERR flag is
set.
This register can be read/written in 8-bit or 1-bit units. After a write access, the
register is cleared.
