PERFORM CONVERSION

Function:

These commands instruct the ADC to perform conversions on the physical input channel point-

ed to by the pointer bits (CSRP2 - CSRP0) in the channel-setup registers. The particular type

of conversion performed is determined by the states of the conversion control bits (the multiple

conversion bit, the loop bit, read convert bit, and the depth pointer bits) in the configuration reg-

ister.
