7.2
The MOD register contains the most recent modulator
data output. The default value corresponds to an
equivalent input of 0V on both ADCs. Each bit in this
register corresponds to one comparator output on one
of the channels.

Modulator Output Register
This register can be written in order to overwrite modulator output data, but any writing here will corrupt the
ADC_DATA on the next three data ready pulses.

This register should be used as a read-only register.
(Note
This register is updated at the refresh rate of DMCLK
(typically, 1 MHz with MCLK = 4 MHz).
