10-BIT A/D CONVERTER (ADC) (Cont’d)
11.6.6 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 hard-
ware when software reads the ADCDRH register
or writes to any bit of the ADCCSR register.
0: Conversion is not complete
1: Conversion complete
Bit 6 = SPEED ADC clock selection
This bit is set and cleared by software. It is used
together with the SLOW bit to configure the ADC
clock speed. Refer to the table in the SLOW bit de-
scription.
Bit 5 = ADON A/D Converter on
This bit is set and cleared by software.
0: A/D converter is switched off
1: A/D converter is switched on
Bit 4:3 = Reserved. Must be kept cleared.
Bit 2:0 = CH[2:0] 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 HIGH (ADCDRH)
Read Only
Reset Value: 0000 0000 (00h)
Bit 7:0 = D[9:2] MSB of Analog Converted Value
CONTROL AND DATA REGISTER LOW (AD-
CDRL)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7:5 = Reserved. Forced by hardware to 0.
Bit 4 = Reserved. Forced by hardware to 0.
Bit 3 = SLOW Slow mode
This bit is set and cleared by software. It is used
together with the SPEED bit to configure the ADC
clock speed as shown on the table below.
Bit 2 = Reserved. Forced by hardware to 0.
Bit 1:0 = D[1:0] LSB of Analog Converted Value
