IF: Interrupt request flag
IM: Interrupt mask
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.
