Calibration Word 10

Calibration word 10 at memory location 2089h contains

the calibration bits for VREF2 DAC span trim

VR2SPCAL<4:0> and the VREF2 DAC span trim

VRSPCAL<4:0>.

The

VR2SPCAL<4:0>

individual adjustment specific to calibrating the VREF2

DAC span. Firmware must read these values and copy

into the VR2SPCAL Special Function Register located

in Bank 2 at 11Ah.

The VRSPCAL<4:0> is an individual adjustment

specific to calibrating the VREF2 DAC span. Firmware

must read these values and copy into the VRSPCAL
