Only STOP - 0x4 and RUN 0x8 are defined in the Snap7 src. What is the reason for that?

SZL-ID W#16#xy24 - Operation Mode and Mode Transition says:

ID of the mode change divided into 4 bits
Bit 0 to 3: Requested mode
Bit 4 to 7: Previous mode
Operating mode IDs of the requested or previous modes:
1H: STOP (update)
2H: STOP (memory reset)
3H: STOP (self initialization)
4H: STOP (internal)
5H. Startup (complete restart)
7H: Restart
8H: RUN
AH: HOLD
DH: DEFECT
