The A/D converter implemented in the MCU is a 6-channel 8-bit A/D converter. The reference voltage (high reference
voltage and low reference voltage) can be selected as coming from external pins (PB6/VRL and PB7/VRH) or internal
power supplies of MCU (VDD and VSS). The VRLand VRH are used to set the minimal and maximal boundaries of the
full-scalerangeoftheA/Dconverter.Ifananaloginputs,VRLorVRHisnotusedforA/Dconversion,italsocanbeused
as a general purpose I/O line. The ADSC (A/D converter status and control register) register is used to set the configu-
rations and A/D clock sources of A/D converter and control the operation of A/D converter.

ACS2~ACS0
These 3 bits are use to select one of eight A/D converter channels for the conversion.
The A/D converter input channels AN0~AN5 are pin-shared with PB0~PB5. PB6/VRL
and PB7/VRH are used for the A/D converter reference inputs. ACS2,ACS1,ACS0 :

ADON
This bit is used to control the enable/disable of A/D converter circuit. If this bit is set to
1 the A/D converter enters operating mode. Otherwise, the A/D converter will be
turned-off
