FUNCTION
A change in temperature does not trigger a VDAC(CODE) calculation. Any VDAC(CODE)
calculation triggered in another way does not include the temperature lookup. This bit setting
simplifies the VDAC(CODE) calculation to VDAC(CODE) = VSET(CODE) (1 + LUTK[K]).
A change in temperature does not trigger a VDAC(CODE) calculation. Any VDAC(CODE)

simplifies the VDAC(CODE) calculation to VDAC(CODE) = VSET(CODE) (1 - LUTK[K]).
A change in the channel 1/channel 2 external temperature sensor reading triggers a
VDAC(CODE) calculation for the corresponding DAC channel. When a VDAC(CODE) calculation
is triggered, the calculation includes the temperature lookup function.
A change in the internal temperature sensor reading triggers a VDAC(CODE) calculation for the

corresponding channel. When a VDAC(CODE) calculation is triggered, the calculation includes
the temperature lookup function.

FUNCTION
No K LUT operations performed. This bit setting simplifies the VDAC(CODE)
calculation to:
VDAC(CODE) = VSET(CODE) (1 + LUTTEMP[TEMP])
The VDAC(CODE) calculation simplifies to:
VDAC(CODE) = VSET(CODE) (1 + LUTK[VSET] x LUTTEMP[TEMP])
The VDAC(CODE) calculation simplifies to:
VDAC(CODE) = VSET(CODE) (1 - LUTK[USRK] x LUTTEMP[TEMP])
The VDAC(CODE) calculation simplifies to:
VDAC(CODE) = VSET(CODE) (1 + LUTK[sense voltage] x LUTTEMP[TEMP])
The VDAC(CODE) calculation simplifies to:
VDAC(CODE) = VSET(CODE) (1 + LUTK[ADCIN_] x LUTTEMP[TEMP])
The VDAC(CODE) calculation simplifies to:
VDAC(CODE) = VSET(CODE) + USRK x LUTK[VSET] x LUTTEMP[TEMP]
The VDAC(CODE) calculation simplifies to:
VDAC(CODE) = VSET(CODE) + USRK x LUTK[sense voltage] x LUTTEMP[TEMP]
The VDAC(CODE) calculation simplifies to:
VDAC(CODE) = VSET(CODE) + USRK x LUTK[ADCIN_] x LUTTEMP[TEMP]
