Primary Channel ADC Data Register
Name: ADC0DAT
Address: 0xFFFF051C
Default value: 0x00000000
Access: Read only
Function: This ADC data MMR holds the 24-bit
conversion result from the primary ADC. The
ADC does not update this MMR if the ADC0
conversion result ready bit (ADCSTA[0]) is
set. A read of this MMR by the MCU clears
all asserted ready flags (ADCSTA[1:0]).
Table 49. ADC0DAT MMR Bit Designations
Bit Description
23:0 ADC0 24-bit conversion result.
Auxiliary Channel ADC Data Register
Name: ADC1DAT
Address: 0xFFFF0520
Default value: 0x00000000
Access: Read only
Function: This ADC data MMR holds the 24-bit
conversion result from the auxiliary ADC.
The ADC does not update this MMR if the
ADC0 conversion result ready bit
(ADCSTA[1]) is set.
Table 50. ADC1DAT MMR Bit Designations
Bit Description
23:0 ADC1 24-bit conversion result.
Primary Channel ADC Offset Calibration Register
Name: ADC0OF
Address: 0xFFFF0524
Default value: Part specific, factory programmed
Access: Read and write
Function: This ADC offset MMR holds a 16-bit offset
calibration coefficient for the primary ADC.
The register is configured at power-on with a
factory default value. However, this register
automatically overwrites if an offset
calibration of the primary ADC is initiated by
the user via bits in the ADCMDE MMR. User
code can write to this calibration register only
if the ADC is in idle mode. An ADC must be
enabled and in idle mode before being
written to any offset or gain register. The
ADC must be in idle mode for at least 23 µs.

Bit Description
15:0 ADC0 16-bit offset calibration value.
Auxiliary Channel ADC Offset Calibration Register
Name: ADC1OF
Address: 0xFFFF0528
Default value: Part specific, factory programmed
Access: Read and write
Function: This offset MMR holds a 16-bit offset
calibration coefficient for the auxiliary
channel. The register is configured at power-
on with a factory default value. However, this
register is automatically overwritten if an
offset calibration of the auxiliary channel is
initiated by the user via bits in the ADCMDE
MMR. User code can write to this calibration
register only if the ADC is in idle mode. An
ADC must be enabled and in idle mode
before being written to any offset or gain
register. The ADC must be in idle mode for
at least 23 µs.
