ADC Interrupt Mask Register
Name:
ADCMSKI
Address:
0xFFFF0504
Default Value:
0x00
Access:
Read/write
Function:
This register allows the ADC interrupt sources to be individually enabled. The bit positions in this register are
the same as the lower eight bits in the ADCSTA MMR. If a bit is set by user code to a 1, the respective interrupt
is enabled. By default, all bits are 0, meaning all ADC interrupt sources are disabled. Note that ADCMSKI[2:0]
should not be set if ADCMSKI[5] is set.
ADC Mode Register
Name:
ADCMDE
Address:
0xFFFF0508
Default Value:
0x00
Access:
Read/write
Function:
The ADC mode MMR is an 8-bit register that configures the mode of operation of the ADC subsystem.

Bit
Description
7 to 6
Not used. These bits are reserved for future functionality and should be written as 0 by user code.
5
ADC enable continuous interrupt.
This bit is set to 1 to enable ADCSTA[5].
This bit is set to 0 by default.
4
Reserved.
3
ADC power mode configuration.
0 = ADC normal mode. If enabled, the ADC operates with normal current consumption yielding optimum electrical performance.
1 = ADC low power mode. If enabled, the ADC operates with reduced current consumption. In this mode, the gain is fixed to 512.
2 to 0
ADC operation mode configuration.
0, 0, 0 = ADC power-down mode. All ADC circuits are powered down.
0, 0, 1 = ADC continuous conversion mode. In this mode, any enabled ADC continuously converts.
0, 1, 0 = ADC single conversion mode. In this mode, any enabled ADC performs a single conversion. The ADC enters idle mode when the
single shot conversion is complete. A single conversion takes two to three ADC clock cycles depending on the chop mode.
0, 1, 1 = ADC idle mode. In this mode, the ADC is fully powered on but is held in reset.
1, 1, 0 = ADC system zero-scale calibration. In this mode, a zero-scale calibration is performed on enabled ADC channels against
an external zero-scale voltage applied to the ADC input pins. The calibration is carried out at the user programmed ADC settings;
therefore, as with a normal, single ADC conversion, it takes the full ADC filter settling time before a fully settled calibration result is
ready. The results (offset coefficients) are available in the ADCxDAT MMR when ADCSTA[15] is set. User software should copy the
result of the conversion to the ADCxOF MMR.
1, 1, 1 = ADC system full-scale calibration. In this mode, a full-scale calibration is performed on enabled ADC channels against an
external full-scale voltage applied to the ADC input pins. The results (gain coefficients) are available in the ADCxDAT MMR when
ADCSTA[15] is set. User software should copy the result of the conversion to the ADCxGN MMR.
Other = reserved.
