SN8F2250B Series  
USB 2.0 Full-Speed 8-Bit Micro-Controller  
4.4 SYSTEM HIGH CLOCK  
The system high clock is from the in circuit PLL. User must select the external oscillator 6MHz X’tal, 12MHz X’tal or  
16MHz X’tal by the code option “Ext_OSC”, and the entire three clock source will input to the on-chip PLL circuit. PLL  
will output 12MHz to system clock (Fosc).  
4.4.1 EXTERNAL HIGH CLOCK  
External high clock includes three modules (Crystal and external clock signal). The start up time of crystal and ceramic  
oscillator is different. The oscillator start-up time decides reset time length.
