Notes 1. When the internal high-speed RAM area is accessed or instruction with no data access
2. When an area except the internal high-speed RAM area is accessed
3. Only when rp = BC, DE or HL
4. Except “r = A”
Remark One instruction clock cycle is one cycle of the CPU clock (f
CPU) selected by the PCC register.
