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.
Remarks 1. One instruction clock cycle is one cycle of the CPU clock (f
control register (PCC).
2. This clock cycle applies to internal ROM program.
3. n is the number of waits when external memory expansion area is read from.
4. m is the number of waits when external memory expansion area is written to.
