3. Operation of FOR ~ NEXT instruction:
a) In the area between FOR ~ NEXT instruction, FOR designating K8 indicates the loop between FOR ~ NEXT
will be executed repeatedly for 8 times before the next instruction is executed.
b) Between FOR ~ NEXT (INC E), E will be 0, 1, 2, …7 plusing 1. Therefore, the 8 VR rotary switch volumes
will be VR0→D100, VR1→D101, VR2→D102…VR7→D107 and be read to designated registers in order.
Remarks:
1. VR refers to Variable Resister.
2. The 2 points of VR rotary switch built in SA/SC/EH/EH2/SV series MPU can be used together with special D and
special M.
