**Syntax**
**ADC** *Rdst, Sar_sel, Mux, Cycles*
- **ADC** *Rdst, Sar_sel, Mux*
- **ADC** *Rdst, Sar_sel, Mux, 0* — deprecated form
**Operands**
- *Rdst* – Destination Register R[0..3], result will be stored to this register
- *Sar_sel* – selected ADC : 0=SARADC0, 1=SARADC1
- *Rdst* – Destination Register R[0..3], result will be stored to this register
- *Sar_sel* – Select ADC: 0 = SARADC1, 1 = SARADC2
- *Mux* - selected PAD, SARADC Pad[Mux+1] is enabled
- *Cycle* – number of cycles used to perform measurement
**Description**
The instruction makes measurements from ADC.
**Examples**::
1: ADC R1, 0, 1, 100 // Measure value using ADC1 pad 2,
// for 100 cycles and move result to R1
1: ADC R1, 0, 1 // Measure value using ADC1 pad 2 and store result into R1
**REG_RD** – read from peripheral register
