The STM32F7 series is one of our very high-performance MCUs. Taking advantage of ST’s ART Accelerator™ as well as an L1 cache, STM32F7 microcontrollers delivers the maximum theoretical performance of the Arm® Cortex®-M7 core, whether the code is executed from embedded Flash or external memory: 1082 CoreMark /462 DMIPS at 216 MHz fCPU.
DCORSEL的设置好像很宽泛，比如下面的代码查datasheet发现在DCOx和MODx的设置为0000时，DCO的范围并不能到4.9Mhz:time::time:__bis_SR_register(SCG0); // Disable the FLL control loopUCSCTL0 = 0x0000; // Set lowest possible DCOx, MODxUCSCTL1 =
