10-BIT A/D CONVERTER (ADC) (Cont’d)
10.8.6 Register Description
CONTROL/STATUS REGISTER (ADCCSR)
Read/Write (Except bit 7 read only)
Reset Value: 0000 0000 (00h)
Bit 7 = EOC End of Conversion
This bit is set by hardware. It is cleared by soft-
ware reading the ADCDRMSB register.
0: Conversion is not complete
1: Conversion complete
Bit 6:5 = PRSC[1:0] ADC clock prescaler selection
These bits are set and cleared by software.
Bit 4 = ADON A/D Converter on
This bit is set and cleared by software.
0: Disable ADC and stop conversion
1: Enable ADC and start conversion
Bit 3:0 = CS[3:0] Channel Selection
These bits are set and cleared by software. They
select the analog input to convert.
*The number of channels is device dependent. Refer to
the device pinout description.

DATA REGISTER (ADCDRMSB)
Read Only
Reset Value: 0000 0000 (00h)
Bit 7:0 = D[9:2] MSB of Analog Converted Value
This register contains the MSB of the converted
analog value.
DATA REGISTER (ADCDRLSB)
Read Only
Reset Value: 0000 0000 (00h)
Bit 7:2 = Reserved. Forced by hardware to 0.
Bit 1:0 = D[1:0] LSB of Analog Converted Value
This register contains the LSB of the converted an-
alog value.
