Absolute VINDPM Threshold
Offset: 2.6V
Range: 3.9V (0001101) – 15.3V (1111111)
Default: 4.4V (0010010)
Note:
Value < 0001101 is clamped to 3.9V (0001101)
Register is read only when FORCE_VINDPM=0 and can
be written by internal control based on relative VINDPM
threshold setting
Register can be read/write when FORCE_VINDPM = 1
