6. System Clock

The system clock source can be selected from 16Mhz crystal or ROSC. For the ROSC,

user should connect two resistors in the pin “XIN” and “XOUT” instead of 16MHZ crystal.

Beside, the clock source select pin “CKSEL” also should be connected to VDD for ROSC.

In order to get an accurate system clock by ROSC, the real time clock source is

recommended to connect a 32768HZ crystal for system clock calibration.
