Hclk to ahb bus
Web系统时钟SYSCLK最大频率为72MHz，它是供STM32中绝大部分部件工作的时钟源。系统时钟可由PLL、HSI或者HSE提供输出，并且它通过AHB分频器分频后送给各模块使用。 HCLK. HCLK为高性能总线AHB（advanced high-performance bus）提供时钟信号。 WebDec 12, 2012 · HSE and PLL. The AHB clock (HCLK) is derived from System clock through configurable prescaler and used to clock the CPU, memory and peripherals mapped on AHB bus (DMA and GPIO). APB1 (PCLK1) and APB2 (PCLK2) clocks are derived from AHB clock through
