Main ADC (DATA0)
Data Register
Read Only
16 Bits or 24 Bits
000000 Hex
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
0000 Hex
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
800000 Hex
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 Regis-
ters 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
5XXXX5 Hex
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 and these are associated with input chan-
nel pairs as outlined in the AD0CON register.
Aux ADC
Offset Register
Read/Write
16 Bits
8000 Hex
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
59XX Hex
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.
Contains an 8-bit byte that is the identifier for the
part.
ID Register
Read
8 Bits
0X Hex
Test Registers
Read/Write
16 Bits
0000 Hex
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.
