A simple 12-bit counter is used to implement this function. It counts up until it
reaches the value loaded in the sampling frequency register.
The counter is enabled by the channel counter enable bits of the global control
register.

Sampling Frequency Register ADC5...0 (Group A) – 0x10 (Read-Write register).

Setting

Bit 11...0

Description – Sampling Frequency Register ADC5...0

0

Value between 0x19 and 0x9C4 to be programmed, respectively matching with maximum
sampling rate (10MHz) and minimum sampling rate (100KHz) of the ADC. ADC0....5 are
sampling at the same rate.
