(1) Crystal Oscillator
The crystal oscillator is used in which the crystal resonator is
connected to the XTAL/EXTAL pin or USB_X1/USB_X2 pin.
One of them is selected according to the clock operating
mode.
(2) Divider 1
Divider 1 divides the output from the crystal oscillator or the
external clock input. The division ratio depends on the clock
operating mode.
(3) PLL Circuit
PLL circuit multiplies the frequency of the output from the
divider 1. The multiplication ratio is set by the frequency
control register.
(4) Divider 2
Divider 2 generates a clock signal whose operating
frequency can be used for the internal clock, the peripheral
clock, and the bus clock. The division ratio of the internal
clock and peripheral clock are set by the frequency control
register. The division ratio of the bus clock is determined by
the clock operating mode and the PLL multiplication ratio.
