I'm curious about what this feature does.
We measure the distortion of each DEVDAC PCB and loaded the resultant coefficients into the ESS and cancel the distortion - this cancellation mode can be Enabled or Bypassed.
As each PCB distortion is different we need to calibrate each board which is time consuming. The calibration coefficients are stored on a local EEPROM on the DEVDAC PCB which can then be read by the system MCU and used to programmer the ESS.
