FAQ
During the program development of the NUC100AN series using the BSP V3.0 or later version, why does the user get stuck in waiting for a stable clock source? How to handle it? Issue Date：2015-11-02
Since the CLKSTATUS register did not exist in the NUC100AN series, when the program executes
while((CLK->CLKSTATUS & CLK_CLKSTATUS_OSC22M_STB_Msk) == 0);
this will cause the program to enter an infinite loop.
The user can change to delay 5ms
CLK_SysTickDelay(5000);
to ensure a stable clock source.
