3.2.1 Oscillation Circuit

The clock signal incoming from crystal oscillator or ceramic resonator via Xin and Xout, or from

external clock via Xin is supplied to Clock Pulse Generator and Prescaler

Internal System Clock for CPU is made by Clock Pulse Generator, and several peripheral clock

is

devided by prescaler

Clock Generation circuit of Crystal Oscillator or Ceramic Resonator is shown in Fig.3.2.2
