Section 11 On-Chip Oscillation Circuits
The clock pulse generator blocks function as follows:
1. PLL Circuit 1: PLL circuit 1 doubles, triples, or leaves unchanged the input clock frequency
2. PLL Circuit 2: PLL circuit 2 doubles, quadruples, or leaves unchanged the input clock
3. Crystal Oscillator: This oscillator is used when a crystal resonator is connected to the XTAL
4. Divider 1: Divider 1 generates a clock at the operating frequency used by the internal or
5. Clock Frequency Control Circuit: The clock frequency control circuit controls the clock
6. Standby Control Circuit: The standby control circuit controls the state of the on-chip oscillator
7. Frequency Control Register: The frequency control register has control bits assigned for the
8. Standby Control Register: The standby control register has bits for controlling the power-down

this is done, the phase of the rising edge of the internal clock is controlled so that it will
synchronize with the phase of the rising edge of the CKIO pin.
