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
CPU
) selected by the processor clock
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.
