8.3.2. Tracking Modes
The AD0TM bit in register ADC0CN enables "delayed conversions", and will delay the actual conversion
start by three SAR clock cycles, during which time the ADC will continue to track the input. If AD0TM is left
at logic 0, a conversion will begin immediately, without the extra tracking time. For internal start-of-conver-
sion sources, the ADC will track anytime it is not performing a conversion. When the CNVSTR signal is
used to initiate conversions, ADC0 will track either when AD0TM is logic 1, or when AD0TM is logic 0 and
CNVSTR is held low. See Figure 8.2 for track and convert timing details. Delayed conversion mode is use-
ful when AMUX settings are frequently changed, due to the settling time requirements described in Section
“8.3.3. Settling Time Requirements” on page 42.
