(4) Explanation of machine cycle field
S shows the number of machine cycles required when skip is performed by an instruction with skip. The
value of S changes as follows:
No skip ....................................................................................................................................................................... S = 0
When instruction to be skipped is 1-byte or 2-byte instruction......................................................................... S = 1
When instruction to be skipped is 3-byte instruction (BR !addr, CALL !addr instruction)............................. S = 2
Note
One machine cycle is required to skip a GETI instruction.
One machine cycle is equivalent to one cycle (=t
CY
) of the CPU clock
Φ
. Three times can be selected by PCC
setting.
