If you just want to display the result you can sum the datah and datal in an int variable and send it to serial port
For example
int result;
result = (DATAH«« + DATAL;

With Keil C51, 16 bit values in two consecutive special function registers can be acessed by the sfr16 data type in a single C instruction. The definitions are not included in standard aduc8xx.h-files and have to be added.
| Code: |
| sfr16 ADCDATA_L_H = 0xD9; |
12 bit data are extracted by bit mask operations, e. g. (ADCDATA_L_H & 0xfff).
