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
control register (PCC).
2. This clock cycle applies to the internal ROM program.
3. n is the number of waits when the external memory expansion area is read.
4. m is the number of waits when the external memory expansion area is written.
