Sets the threshold for comparison of the value to detect over
temperature measurements. Two's complement value.
The value entered in this field compares directly against the value
from the DIETEMP register to determine if an over temperature
condition exists. Conversion factor: 7.8125 m°C/LSB.
7.6.1.18 Power Over-Limit Threshold (PWR_LIMIT) Register (Address = 11h) [reset = FFFFh]
The PWR_LIMIT register is shown in Table 7-22.

Sets the threshold for comparison of the value to detect power over-
limit measurements. Unsigned representation, positive value only.
The value entered in this field compares directly against the value
from the POWER register to determine if an over power condition
exists. Conversion factor: 256 × Power LSB.
