Note: Bits in the interrupt control bits area and register flag area are set by the SEM or SEMD
instruction, reset by the REM or REMD instruction, and tested by the TM or TMD instruction.
Other instructions have no effect.
However, note the following usage limitations of RAM bit manipulation instructions.
SEM/SEMD

Note:
WDON is reset only by MCU reset.
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.
