Notes 1. When the internal high-speed RAM area is accessed or for an 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”
Remarks 1. One instruction clock cycle is one cycle of the CPU clock (f
CPU) selected by the processor clock control
register (PCC).
2. This clock cycle applies to the internal ROM program.
