Notes 1. For instructions that access the internal high-speed RAM area or perform no data access
2. For instructions that access an area other than the internal high-speed RAM area
3. Only when rp = BC, DE, or HL
4. Except when "r = A"
Remarks 1. One clock in the "Clock" columns is equal to one cycle of the CPU clock (f
clock control register (PCC).
2. The values in the "Clock" column assumes that the internal ROM area contains programs.
3. n indicates wait cycles to be inserted when an external expansion memory area is read from.
4. m indicates wait cycles to be inserted when an external expansion memory area is written to.
