在手册 P 263 中：
- Bits 27:24 MCOSEL[3:0]: Microcontroller clock output
- Set and cleared by software.
- 0000: MCO output disabled, no clock on MCO
- 0001: SYSCLK system clock selected
- 0010: MSI clock selected.
- 0011: HSI16 clock selected.
- 0100: HSE clock selected
- 0101: Main PLL clock selected
- 0110: LSI clock selected
- 0111: LSE clock selected
- 1000: Internal HSI48 clock selected
但真正的顺序是
- 0000: MCO output disabled, no clock on MCO
- 0001: LSE clock selected
- 0010: LSI clock selected
- 0011: HSE clock selected
- 0100: HSI16 clock selected.
- 0101: Main PLL clock selected
- 0110: SYSCLK system clock selected
- 0111: MSI clock selected.
- 1000: HSI48 clock selected
这是 MCO 输出的 CubeMX 多路复用器设置中的顺序。
