ADC Channel Data Output

Registers

The ADC Channel Data Output registers always

contain the most recent A/D conversion data for each

channel. These registers are read-only. They can be

accessed independently or linked together (with

READ<1:0> bits). These registers are latched when an

ADC read communication occurs. When a data ready

event occurs during a read communication, the most

current ADC data is also latched to avoid data

corruption issues. The three bytes of each channel are

updated synchronously at a DRCLK rate. The three

bytes can be accessed separately, if needed, but are

refreshed synchronously.
