DIAG
select[3:0]
DIAG select selects the set of diagnostic signals that can be made available on MEASOUT. First, use MEASOUT
addressing (DPS Register 1) to select either the DIAG A or the DIAG B node to be made available on MEASOUT.

VPTAT low/VPTAT high are temperature sensor devices in the middle of the enabled power stage, which gives a
voltage level that can be mapped back to the VTSD low and VTSD high reference points to get a temperature
value. These sensors are used in the thermal shutdown feature. See the
VMID code is the midscale voltage of the DACs; the offset DAC has a direct effect on this voltage level.
VMIN code is the zero-scale voltage of the DACs; again the offset DAC has a direct effect.

TSENSE
select[3:0]
The following codes allow selection of one of three sets of eight thermal diodes. The D+ of the selected thermal
diode is available on the GPO pin; the D is on the AGND.
These thermal diodes are located across the die, in the cool parts and in the power stages. Diodes [16:23] are located
in the force amplifier NPNs (power output devices for supplying current). Similarly, Diodes [24:31] are located in
the force amplifier PNP devices (output devices for sinking current).
