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
3. Except “r = A”
Remarks 1. One instruction clock cycle is one cycle of the CPU clock (f
CPU
) selected by the PCC register.
2. This clock cycle applies to internal ROM program.
