CAh

CBh

BIT 7

BIT 0

The digital value used for APC2 DAC. It is the result of LUT6 plus APC2 OFFSET times 4 recalled from Table

06h (Registers F8h–FFh) at the adjusted memory address found in TINDEX. This register is updated at the end

of the temperature conversion.

APC2 DAC = LUT6 + APC2 OFFSET x 4
