The PLL frequency synthesizer generates the PLL clock based on the main clock. The PLL clock can be
used as clock source for the CPU clock and peripheral function clock.
The PLL frequency synthesizer stops after reset. When the PLC07 bit is set to "1" (PLL on), the PLL
frequency synthesizer starts operating. Wait
The PLL clock can either be the clock output from the voltage controlled oscillator (VCO) divided-by-2 or
divided-by-3. When the PLL clock is used as a clock source for the CPU clock or peripheral function
clock, set each bit as is shown in Table 9.3. Figure 9.12 shows the procedure to use the PLL clock as the
CPU clock source.
To enter wait or stop mode, set the CM17 bit to "0" (main clock as CPU clock source), set the PLC07 bit
in the PLC0 register to "0" (PLL off) and then enter wait or stop mode.
