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 is the length of 1 clock cycle of the CPU clock (fCPU) 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.
