User manual
The ADC is configured using the following registers:
Basic clocking for the A/D converters is provided by the APB clock (PCLK). A
programmable divider is included in each converter, to scale this clock to the 4.5 MHz
(max) clock needed by the successive approximation process. A fully accurate conversion
requires 11 of these clocks.

Remark: On reset, the ADC is disabled. To enable the ADC, first set the PCADC bit,
and then enable the ADC in the AD0CR register (bit PDN)
