IE: Interrupt enable flag
SP: Stack pointer
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.

Note: WDON is always reset in active mode.
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.
