11.1 Clock Generator
11.1.1 Overview
As shown in Figure 11.1, the clock generator produces the basic clock pulses which provide the system clock to be
supplied to the CPU and the peripheral hardware. It contains main/sub-frequency clock oscillator. The main/sub clock
operation can be easily obtained by attaching a crystal between the XIN/SXIN and XOUT/SXOUT pin, respectively.
The main/sub clock can be also obtained from the external oscillator. In this case, it is necessary to put the external
clock signal into the XIN/SXIN pin and open the XOUT/SXOUT pin. The default system clock is 1MHz INT-RC
Oscillator and the default division rate is sixteen. In order to stabilize system internally, it is used 1MHz INT-RC
oscillator on POR.
− Calibrated Internal RC Oscillator (8 MHz )
• INT-RC OSC/2 (8 MHz)
• INT-RC OSC/4 (4 MHz)
• INT-RC OSC/8 (2 MHz)
• INT-RC OSC/16 (1 MHz, Default system clock)
• INT-RC OSC/32 (0.5 MHz)
− Main Crystal Oscillator (0.4~10 MHz)
− Sub Crystal Oscillator (32.768 kHz)
− Phase Look Loop ( 1.024~8.192 MHz)
− Internal WDTRC Oscillator (5 kHz)
