8-BIT A/D CONVERTER (ADC) (Cont’d)
11.4.6 Register Description
CONTROL/STATUS REGISTER (ADCCSR)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7 = EOC
Conversion Complete
This bit is set by hardware. It is cleared by soft-
ware reading the result in the DR register or writing
to the CSR register.
0: Conversion is not complete
1: Conversion can be read from the DR register
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 and Amplifier On
This bit is set and cleared by software.
0: A/D converter and amplifier are switched off
1: A/D converter and amplifier are switched on
Bit 4:3 = Reserved.
must always be cleared.
Bits 2:0 = CH[2:0]
Channel Selection
These bits are set and cleared by software. They
select the analog input to convert.
Notes:
1. The number of pins AND the channel selection
varies according to the device. Refer to the device
pinout.
2. A write to the ADCCSR register (with ADON set)
aborts the current conversion, resets the EOC bit
and starts a new conversion.
DATA REGISTER (ADCDR)
Read Only
Reset Value: 0000 0000 (00h)
Bits 7:0 = D[7:0]
Analog Converted Value
This register contains the converted analog value
in the range 00h to FFh.
Note: Reading this register reset the EOC flag.
AMPLIFIER CONTROL REGISTER (ADCAMP)
Read/Write
Reset Value: 0000 0000 (00h)
Bit 7:4 = 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 = AMPSEL
Amplifier Selection Bit
This bit is set and cleared by software.
0: Amplifier is not selected
1: Amplifier is selected
Note: When AMPSEL=1 it is mandatory that fADC
be less than or equal to 2 MHz.
Bit 1:0 = Reserved. Forced by hardware to 0.
Note: If ADC settings are changed by writing the
ADCAMP register while the ADC is running, a
dummy conversion is needed before obtaining re-
sults with the new settings.
