4.4.1.1 CRYSTAL/CERAMIC
Crystal/Ceramic devices are driven by XIN, XOUT pins. For high/normal/low frequency, the driving currents are
different. High_Clk code option supports different frequencies. 12M option is for high speed (ex. 12MHz). 4M option is
for normal speed (ex. 4MHz).

 Note: Connect the Crystal/Ceramic and C as near as possible to the XIN/XOUT/VSS pins of
micro-controller.
4.4.1.2 RC
Selecting RC oscillator is by RC option of High_Clk code option. RC type oscillator’s frequency is up to 10MHz. Using
“R” value is to change frequency. 50P~100P is good value for “C”. XOUT pin is general purpose I/O pin.
