**Description** **Description**
The instruction makes measurements from ADC. The instruction makes measurements from ADC.
**Examples**:: **Examples**::
1: ADC R1, 0, 1, 100 // Measure value using ADC1 pad 2, 1: ADC R1, 0, 1 // Measure value using ADC1 pad 2 and store result into R1
// for 100 cycles and move result to R1
