The lower seven bits of POHh contain the most significant bits of the 15-bit power-on hours measurement. The value in POHh
should be combined with the eight-bit power-on hours low byte, POHl, to yield the complete result.
The most significant bit of POHh, POHFLT, is an error flag. If POHFLT is set, the power-on hour meter data has been
corrupted and should be ignored.
It is recommended that a two-byte sequential (block) SMBus read operation be performed on POHh and POHl to insure
coherency between the two registers.
This register is non-volatile and will be maintained through power and reset cycles, including unanticipated power failures.

Operation
1 = fault: the power-on hours value is corrupted and cannot
be relied upon
0 = no fault: the power-on hours value is correct

When the A/D conversion for a given parameter is completed and the results available to the host, the appropriate data ready
flag will be set. The flag will be cleared when the host reads the corresponding result register.
