STATUS_WORD (79h)
Definition: Returns a summary of the device’s fault status. Based on the information in these bytes, the host can get more information
by reading the appropriate status registers. A fault in either output will be reported here. The low byte of the STATUS_WORD contains
the same information as the STATUS_BYTE (78h) command.

IOUT
An output voltage fault has occurred.
An output current fault has occurred.
13
INPUT
An input voltage fault has occurred.
12
MFR_SPECIFIC
A manufacturer specific event has occurred.
11

OFF
This bit is asserted if the unit is not providing power to the output,
regardless of the reason, including simply not being enabled.
5
VOUT_OV_FAULT
An output overvoltage fault has occurred.
4
IOUT_OC_FAULT
An output overcurrent fault has occurred.
3
VIN_UV_FAULT

TEMPERATURE
A temperature fault or warning has occurred.
1
CML
A communications, memory or logic fault has occurred.
0
None of the Above
A status change other than those listed above has occurred.
NOTE:
8. If the POWER_GOOD# bit is set, this indicates that the POWER_GOOD signal, if present, is signaling that the output power is not good.
