63 / 107 page  NUC100/120xxxDN Aug 31, 2015 Page 63 of 107 Rev 1.01 6.3.3 System Clock and SysTick Clock The system clock has 5 clock sources which were generated from clock generator block. The clock source switch depends on the register HCLK_S (CLKSEL0[2:0]). The block diagram is shown in Figure 6-12. 111 011 010 001 PLLFOUT 32.768 kHz 4~24 MHz 10 kHz HCLK_S (CLKSEL0[2:0]) 22.1184 MHz 000 1/(HCLK_N+1) HCLK_N (CLKDIV[3:0]) CPU in Power Down Mode CPU AHB APB CPUCLK HCLK PCLK Note: Before clock switching, both the pre-selected and newly selected clock sources must be turned on and stable. Figure 6-12 System Clock Block Diagram The clock source of SysTick in Cortex ® -M0 core can use CPU clock or external clock (SYST_CSR[2]). If using external clock, the SysTick clock (STCLK) has 5 clock sources. The clock source switch depends on the setting of the register STCLK_S (CLKSEL0[5:3]). The block diagram is shown in Figure 6-13. 111 011 010 001 4~24 MHz 32.768 kHz 4~24 MHz HCLK STCLK_S (CLKSEL0[5:3]) STCLK 22.1184 MHz 000 1/2 1/2 1/2 Note: Before clock switching, both the pre-selected and newly selected clock sources must be turned on and stable.
