23:0 | FSCAL[23:0] | R/W | 400000h | Full-Scale Calibration Three 8-bit registers compose the 24-bit full scale calibration word. The 24-bit word format is straight binary. The ADC divides the 24-bit value by 400000h to derive the gain coefficient. The ADC multiplies the gain coefficient by the 32-bit conversion result after the offset operation. |
