Hclk clock frequency

WebFCLK and HCLK are synchronous to each other.FCLK is a free running version of HCLK.For more information, see Power Management. FCLK and HCLK must be balanced with respect to each other, with equal latencies into the processor.. The processor is integrated with components for debug and trace. Your macrocell might contain some, or … WebDec 18, 2024 · Clock Configuration. We configure the clock tree so that the clock frequency (HCLK) of the microcontroller is 84 MHz, handling frequency divisor and multiplier of PLLCLK. The bus to which the timers are connected (APB1 timer and APB2 timer clocks) is also at 84 MHz. Timer Configuration
