Note: WDON is reset by MCU reset or by
STOPC
enable for stop mode cancellation.
The REM or REMD instuction must not be executed for CMSF during comparator
operation. DTON is always reset in active mode.
If the TM or TMD instruction is executed for the inhibited bits or non-existing bits,
the value in ST becomes undefined.
