The STATUS_MFR_SPECIFIC command returns 1 byte of information with a summary of the reason for a fault. The
STATUS_MFR_SPECIFIC message content is described in Table 24.
The STATUS_FANS_1_2 command returns 1 byte of information with the status of the fan. The STATUS_FANS_1_2
command is described in Table 25.
The READ_VOUT command returns the actual measured (not commanded) output voltage. READ_VOUT is measured
and updated every 5ms. The 2 data bytes are in DIRECT format.
The READ_IOUT command returns the latest measured current value. READ_IOUT is measured and updated every
200ms. The 2 data bytes are in DIRECT format.
The READ_TEMPERATURE_1 command returns the temperature returned from the temperature sensor. The value of
READ_TEMPERATURE_1 does not have offset from MFR_TEMP_SENSOR_CONFIG added. READ_TEMPERATURE_1
returns 7FFFh if the sensor is faulty and 0000h if the sensor is disabled. READ_TEMPERATURE_1 is measured and
updated once a second. The 2 data bytes are in DIRECT format.

Fan 1 fault.
This bit always returns a 0.
Fan 1 warning.
These bits always return a 0.
This bit is set if the power supply is off (due to either a fault or sequencing delay; this bit is
not set if the power supply is disabled).
Overtemperature warning.
Overtemperature fault.
A watchdog reset has occurred.
This bit is set if the device cannot properly close-loop margin the power supply.
Power-supply voltage has fallen from POWER_GOOD_ON to less than POWER_GOOD_OFF.
IOUT overcurrent fault.
IOUT overcurrent warning.
