WM[15:0] — Watchdog Modulus Field
The prescaler counter is reset anytime a new value is loaded into the
watchdog counter and also during reset.

Write:
The read-always, write-once WM[15:0] field contains the modulus
that is reloaded into the watchdog counter by a service sequence.
Once written, the WM[15:0] field is not affected by further writes
except in debug mode. Writing to WMR immediately loads the new
modulus value into the watchdog counter. The new value is also used
at the next and all subsequent reloads. Reading WMR returns the
value in the modulus register.
Reset initializes the WM[15:0] field to 0xFFFF.
