The ADC Channel Data Output registers always con-
tain 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 corrup-
tion 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.
