(4) Explanation of the machine cycle column
S represents the number of machine cycles required when a skip instruction with the skip function performs
a skip operation. S assumes one of the following values:
• When no skip operation is performed: S = 0
• When a 1-byte instruction or 2-byte instruction is skipped: S = 1
• When a 3-byte instruction Note is skipped: S = 2
Note 3-byte instruction: BR !addr, BRA !addr1, CALL !addr, and CALLA !addr1 instructions
Caution The GETI instruction is skipped in one machine cycle.
One machine cycle is equal to one cycle (t
CY
) of the CPU clock ( F ), and four different machine cycles are
available for selection according to the PCC setting. (See Figure 5-12.)
