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.
When the internal high-speed RAM area is accessed or for an instruction with no data access
When an area except the internal high-speed RAM area is accessed
control register (PCC).
