The Questionable Status Register is a 16-bit register that stores information about
questionable events or status during power supply operation. That is, bits in these
registers may indicate that the output of the supply is of undesirable or questionable
quality.
The Questionable Status data structure consists of a questionable status register and
sub-registers representing the status of the voltage and current, power and
temperature.
Figure 4.2 gives an overview of the Questionable Status data structure. The “+”
represents the logical summation of bits in a register. Table 4.7, Table 4.8, and Table
4.9 describe the meanings of each bit as well as the bit number and bit weight.
