78K0/Kx2
(2) Processor clock control register (PCC)
R01UH0008EJ0401 Rev.4.01
Jul 15, 2010
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.
