Description
System Clock Divider
Minimum 4-bit divider value for system clock. The reset value is
hardware-dependent. See the RCC register for how to change the
system clock divisor using the SYSDIV bit.
Value Description
0x1 Specifies an 80-MHz CPU clock with a PLL divider of 2.5.
0x2 Specifies a 66.67-MHz CPU clock with a PLL divider of 3.
0x3 Specifies a 50-MHz CPU clock with a PLL divider of 4.
0x7 Specifies a 25-MHz clock with a PLL divider of 8.
0x9 Specifies a 20-MHz clock with a PLL divider of 10.
0x3
Max ADC1 Speed
