MCO Yes. microcontroller clock output Is a microcontroller clock output pin, in the The STM32 F1 series is composed of PA8 The main function of the reuse is to provide a clock externally, which is equivalent to an active crystal oscillator. MCO The clock source can be: PLLCLK\/2, HSI, HSE, SYSCLK, whichever is configured by the clock register. The bit of... 26-24: MCO[2:0] Decision.
In addition to the function of providing the clock externally, we can also monitor it through the oscilloscope. MCO Pin the clock output to verify that our system clock configuration is correct.
The mco chip is a Central Process Unit (Central Process Unit; The frequency and specifications of CPU are appropriately reduced, and peripheral interfaces such as memory, counter (Timer), USB, A\/D conversion, UART, PLC, DMA, and even LCD driver circuits are integrated on a single chip to form a chip-level computer, which can be controlled in different combinations for different applications. Such as mobile phones, PC peripherals, remote controls, to automotive electronics, industrial stepper motors, robot arm control, etc., MCo can be seen.
