      Current Channel ADC Control Register
      Name:
      ADC0CON
      Address:
      0xFFFF050C
      Default Value:
      0x0002
      Access:
      Read/write
      Function:
      The current channel ADC control MMR is a 16-bit register that is used to configure the I-ADC.
      Note:
      If the current ADC is reconfigured via ADC0CON, the voltage/temperature ADC is also reset.

      Bit
      Description
      15
      Current channel ADC enable.
      This bit is set by user code to enable the I-ADC.
      This bit is cleared by user code power-down the I-ADC and resets the respective ADC ready bit in the ADCSTA MMR to 0.
      14 to 13
      IIN current source enable.
      00 = current sources off.
      01 = enables 50 μA current source on IIN+.
      10 = enables 50 μA current source on IIN.
      11 = enables 50 μA current source on both IIN and IIN+.
      12 to 10
      Not used. These bits are reserved for future functionality and should be written as zero.
      9
      Current channel ADC output coding.
      This bit is set by user code to configure I-ADC output coding as unipolar.
      This bit is cleared by user code to configure I-ADC output coding as twos complement.
      8
      Not used. This bit is reserved for future functionality and should be written as zero.
      7 to 6
      Current channel ADC input select.
      00 = IIN+, IIN.
      01 = IIN, IIN = diagnostic, internal short configuration.
      10 = VREF/136, 0 V, diagnostic, test voltage for gain settings <512. If the (REG_AVDD, AGND) divided-by-two reference is selected,
      REG_AVDD is used instead of VREF with this I-ADC input selection. This leads to ADC0DAT scaled by two.
      11 = not defined.
      5
      Reserved.
      4
      Current channel ADC reference select.
      0 = internal, 1.2 V precision reference selected.
      1 = (REG_AVDD, AGND) divided-by-two selected.
      3 to 0
      Current channel ADC gain select. Note: nominal I-ADC full-scale input voltage = (VREF/gain).
      0001 = I-ADC gain of 2. This setting is tested for functionality only; therefore, it does not appear in the electrical specifications.
      0010 = I-ADC gain of 4.
      0011 = I-ADC gain of 8.
      0100 = I-ADC gain of 16.
      0101 = I-ADC gain of 32.
      0110 = I-ADC gain of 64.
      0111 = I-ADC gain of 128.
      1000 = I-ADC gain of 256.
      1001 = I-ADC gain of 512.
      Other = I-ADC gain is undefined.
