This peripheral has up to 16 multiplexed analog input channels (refer to device pin out description) that allow the peripheral to convert the analog voltage levels from up to 16 different sources. The result of the conversion is stored in a 8-bit Data Register. The A/D converter is controlled through a Control/Status Register. 10.8.2 Main Features s 8-bit conversion s Up to 16 channels with multiplexed input s Linear successive approximation s Data register (DR) which contains the results s Conversion complete status flag s On/off bit (to reduce consumption) The block diagram is shown in Figure 62. 10.8.3 Functional Description 10.8.3.1 Analog Power Supply VDDA and VSSA are the high and low level refer- ence voltage pins. In some devices (refer to device pin out description) they are internally connected to the VDD and VSS pins. Conversion accuracy may therefore be impacted by voltage drops and noise in the event of heavily loaded or badly decoupled power supply lines. See electrical characteristics section for more de- tails. Figure 62.
