5.3.2. Tracking Modes
According to Table 5.1, each ADC0 conversion must be preceded by a minimum tracking time for the con-
verted result to be accurate. 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 conver-
sion is preceded by a tracking period of 3 SAR clocks (after the start-of-conversion signal). When the
CNVSTR signal is used to initiate 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 settings are frequently changed, due to the settling time requirements
described in Section “5.3.3. Settling Time Requirements” on page 53.
