5.3.2. Tracking Modes
The AD0TM bit in register ADC0CN controls the ADC0 track-and-hold mode. In its default state, the ADC0
input is continuously tracked, except when a conversion is in progress. When the AD0TM bit is logic 1,
ADC0 operates in low-power track-and-hold mode. In this mode, each conversion is preceded by a track-
ing period of 3 SAR clocks (after the start-of-conversion signal). When the CNVSTR signal is used to initi-
ate conversions in low-power tracking mode, ADC0 tracks only when CNVSTR is low; conversion begins
on the rising edge of CNVSTR (see Figure 5.4). Tracking can also be disabled (shutdown) when the device
is in low power standby or sleep modes. Low-power track-and-hold mode is also useful when AMUX set-
tings are frequently changed, due to the settling time requirements described in
Time Requirements” on page
