(2) Processor clock control register (PCC)
120
This register is used to select the CPU clock, the division ratio, and operation mode for subsystem clock.
PCC is set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets PCC to 01H.
The fastest instruction can be executed in 2 clocks of the CPU clock in the 78K0/LF2. Therefore, the relationship
between the CPU clock (f
