fHCLK = 72 MHz, fAPB1 = fHCLK/2, fAPB2 = fHCLK, default prescaler value for each peripheral.

Specific conditions for DAC: EN1, EN2 bits in the DAC_CR register are set to 1 and the converted value

set to 0x800.

Specific conditions for ADC: fHCLK = 56 MHz, fAPB1 = fHCLK/2, fAPB2 = fHCLK, fADCCLK = fAPB2/4, ADON bit

in the ADC_CR2 register is set to 1.
