Result

The ADCn.RESL and ADCn.RESH register pair represent the 16-bit value, ADCn.RES. The low byte [7:0] (suffix L) is accessible at the original offset. The high byte [15:8] (suffix H) can be accessed at offset + 0x01.

If the analog input is higher than the reference level of the ADC, the 10-bit ADC result will be equal the maximum value of 0x3FF. Likewise, if the input is below 0V, the ADC result will be 0x000. As the ADC cannot produce a result above 0x3FF values, the accumulated value will never exceed 0xFFC0 even after the maximum allowed 64 accumulations.

Bits 15:8 – RES[15:8][7:0]: Result high byte

Result high byte

These bits constitute the MSB of ADCn.RES register, where the MSb is RES[15]. The ADC itself has 10-bit output, ADC[9:0], where the MSb is ADC[9]. The data format in ADC and Digital Accumulation is 1’s complement, where 0x0000 represents the zero and 0xFFFF represents the largest number (full scale).

Bits 7:0 – RES[7:0][7:0]: Result low byte

Result low byte

These bits constitute the LSB of ADC/Accumulator Result, (ADCn.RES) register. The data format in ADC and Digital Accumulation is 1’s complement, where 0x0000 represents the zero and 0xFFFF represents the largest number (full scale).
