2.1.14 ASB Advanced Options - ADC results

This option exposes the RESULT port from the analog block. This port represents the (ADC) result value for the most recently sampled channel.

The ADC result bus provides a decimal representation of the measured value for Voltage, Current, and Differential Voltage peripherals. For temperature peripherals, the value is expressed in degrees Kelvin. For more information, see the ASB - Calculating a Threshold section.

Table 2-9. ADC Result Signal
Port NameDirectionDescription
ADC_RESULT[11:0]OutputADC result bus. These signals comprise the conversion result from the ADC.

The valid bits of the ADC_RESULT bus depend on the selected ADC resolution:

  • 12‑bit mode: Bits [11:0] are used.
  • 10‑bit mode: Bits [11:2] are used; bits [1:0] are grounded.
  • 8‑bit mode: Bits [11:4] are used; bits [3:0] are grounded.
