Detailed Description

Macro Definition Documentation

◆ STK_CSR_CLKSOURCE

#define STK_CSR_CLKSOURCE (1 << STK_CSR_CLKSOURCE_LSB)

CLKSOURCE: Clock source selection for 0, SysTick uses the IMPLEMENTATION DEFINED external reference clock.

for 1, SysTick uses the processor clock. If no external clock is provided, this bit reads as 1 and ignores writes.
