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 ADSF during A/D conversion.
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 invalid.
