7.2.2. Tracking Modes
The AD2TM bit in register ADC2CN controls the ADC2 track-and-hold mode. In its default state, the ADC2
input is continuously tracked, except when a conversion is in progress. When the AD2TM bit is logic 1,
ADC2 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 CNVSTR2 signal is used to ini-
tiate conversions in low-power tracking mode, ADC2 tracks only when CNVSTR2 is low; conversion
begins on the rising edge of CNVSTR2 (see Figure 7.3). 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 settings are frequently changed, due to the settling time requirements described in
“7.2.3. Settling Time Requirements” on page
