14:0 Divider
ADM DIVIDER controls the AD converter’s sampling frequency. To gather one sample, 128 × n clock
cycles are used (n is value of AD DIV). The lowest usable value is 4, which gives a 48 kHz sample rate
when CLKI is 24.576 MHz. When ADM POWERDOWN is 1, the A/D converter is turned off.
AD DATA contains the latest decoded A/D value.
