Function
Main ADC (DATA0)
Data Register
Read Only
16 Bits or 24 Bits
0x00 0000
Provides the most up-to-date conversion result from
the main ADC. Main ADC data register length
can be programmed to be 16-bit or 24-bit.
Aux ADC (DATA1)
Data Register
Read Only
16 Bits
0x0000
Provides the most up-to-date conversion result from
the auxiliary ADC. Aux ADC data register length is
16 bits.
Main ADC
Offset Register
Read/Write
24 Bits
0x80 0000
Contains a 24-bit word that is the offset calibration
coefficient for the part. The contents of this register
are used to provide offset correction on the output
from the digital filter. There are three offset registers
on the part and these are associated with input channel
pairs as outlined in the AD0CON register.
Main ADC
Gain Register
Read/Write
24 Bits
0x5X XXX5
Contains a 24-bit word that is the gain calibration
coefficient for the part. The contents of this register
are used to provide gain correction on the output
from the digital filter. There are three Gain registers
on the part, which are associated with input channel
pairs as outlined in the AD0CON register.
Aux ADC
Offset Register
Read/Write
16 Bits
0x8000
Contains a 16-bit word that is the offset calibration
coefficient for the part. The contents of this register
are used to provide offset correction on the output
from the digital filter.
Aux ADC
Gain Register
Read/Write
24 Bits
0x59XX
Contains a 16-bit word that is the gain calibration
coefficient for the part. The contents of this register
are used to provide gain correction on the output
from the digital filter.
ID Register
Read
8 Bits
0x0X
Contains an 8-bit byte that is the identifier for the part.
Test Registers
Read/Write
16 Bits
0x0000
Controls the test modes of the part, which are used
when testing the part. The user is advised not to
change the contents of these registers.
