ADC Noise Canceler
Function
1142E–AVR–02/03
Figure 61. ADC Timing Diagram, Free Run Conversion
Table 39. ADC Conversion Time
The ADC features a Noise Canceler that enables conversion during ADC Noise Reduc-
tion mode (see “Sleep Modes” on page 35) to reduce noise induced from the CPU core
and other I/O peripherals. If other I/O peripherals must be active during conversion, this
mode works equivalently for Idle mode. To make use of this feature, the following proce-
dure should be used:
1. Make sure that the ADC is enabled and is not busy converting. Single Conver-
2. Enter ADC Noise Reduction mode (or Idle mode). The ADC will start a conver-
3. If no other interrupts occur before the ADC conversion completes, the ADC inter-
