10-BIT A/D CONVERTER (ADC) (Cont’d)
11.7.6 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 ADCDRH register or writing to
any bit of the ADCCSR register.
0: Conversion is not complete
1: Conversion complete
Bit 6 = SPEED A/D clock selection
This bit is set and cleared by software.
Table 22. A/D Clock Selection
1)
setting the ADON bit.
2)
Bit 5 = 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 4 = SLOW A/D Clock Selection
This bit is set and cleared by software. It works to-
gether with the SPEED bit. Refer to
118/172
EOC SPEED ADON SLOW
The SPEED and SLOW bits must be updated before

Bit 2:0 = CH[2:0] Channel Selection
These bits are set and cleared by software. They
select the analog input to convert.
DATA REGISTER (ADCDRH)
Read Only
Reset Value: 0000 0000 (00h)
Bit 7:0 = D[9:2] MSB of Analog Converted Value
DATA REGISTER (ADCDRL)
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
