CHAPTER 6 CLOCKS
6.1
Clocks
The F2MC-16FX MCU offers up to 4 different clock sources (RC clock, Main clock, PLL
clock and Sub clock). Flexible clock dividers allow an independent setting of the Bus
clock (for the internal bus with the CPU and memories) and for the Peripheral clocks
frequencies.
The Sub oscillator is not included in all F2MC-16FX MCUs. The functions regarding the
Sub oscillator and the Sub clock described in this hardware manual are not available for
MCUs without Sub oscillator. The corresponding settings have no effect.
