6. System Clock
The system clock source also 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.
