67 / 236 page  2016 Microchip Technology Inc. DS20005619A-page 67 MCP19124/5 9.11 Calibration Word 11 Calibration word 11 at memory location 208Ah contains the calibration bits for the 4V LDO (AVDD) trim AVDDCAL<3:0> and the offset voltage of the analog test buffer BUFF<7:0>. AVDD supplies the internal analog circuitry and is the default ADC Reference voltage. Firmware must read these values and copy into the AVDDCAL Special Function Register located in Bank 3 at 19Dh. Also stored at address 208Ah is the Analog test MUX buffer offset value. This is an 8 bit, 2’s complement word that represents the buffer’s offset voltage in units of mV. This value can be used to correct for buffer offset of the analog test signal measurements. See Section 8.0 “System Bench Testing” for test signal details.
