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 cannot be guaranteed.
Bits in the interrupt control bits area and register flag area can be set and reset by the
SEM/SEMD and REM/REMD instructions, and tested with the TM/TMD instructions.
Other instructions have no effect on these bits. Note the following restrictions for each
bit.
