Data register high (ADCDRH)
Read Only
Reset Value: xxxx xxxx (xxh)
Bits 7:0 = D[9:2] MSB of Analog Converted Value
AMP control/data register low (ADCDRL)
Read/Write
Reset Value: 0000 00xx (0xh)
Bits 7:5 = Reserved. Forced by hardware to 0.
Bit 4 = AMPCAL Amplifier Calibration Bit
This bit is set and cleared by software. User is suggested to use this bit to calibrate the ADC
when amplifier is ON. Setting this bit internally connects amplifier input to 0 V. Hence,
corresponding ADC output can be used in software to eliminate amplifier-offset error.
0: Calibration off
1: Calibration on (The input voltage of the amp is set to 0V)
It is advised to use this bit to calibrate the ADC when the amplifier is ON. Setting this bit
internally connects the amplifier input to 0v. Hence, the corresponding ADC output can be
used in software to eliminate an amplifier-offset error.
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.
