The IOUT_OC_WARN_LIMIT command sets the value of the current that causes an overcurrent warning. This value is
typically less than the overcurrent fault threshold in IOUT_OC_FAULT_LIMIT. The 2 data bytes are in DIRECT format.
In response to violation of the IOUT_OC_WARN_LIMIT, the device does the following:
1) Sets the NONE OF THE ABOVE bit in STATUS_BYTE.
2) Sets the NONE OF THE ABOVE, IOUT, and MFR bits in STATUS_WORD.
3) Sets the OC_WARN bit in STATUS_MFR_SPECIFIC.
4) Notifies the host using ALERT assertion (if enabled in MFR_MODE).
The IOUT_OC_FAULT_LIMIT command sets the value of the current that causes an overcurrent fault. The factory
default value for IOUT_OC_FAULT_LIMIT is 0000h. This value disables the device from measuring current. Any nonzero
positive value written to IOUT_OC_FAULT_LIMIT causes the device to enable current measurement. The 2 data bytes
are in DIRECT format. In response to violation of the IOUT_OC_FAULT_LIMIT, the device does the following:
1) Sets the IOUT_OC bit in STATUS_BYTE.
2) Sets the IOUT, IOUT_OC, and MFR bits in STATUS_WORD.
3) Sets the OC_FAULT bit in STATUS_MFR_SPECIFIC.
4) Responds as specified in the MFR_FAULT_RESPONSE.
5) Notifies the host using ALERT assertion (if enabled in MFR_MODE).
The OT_FAULT_LIMIT command sets the temperature, in degrees Celsius, of the selected temperature sensor at which
an overtemperature fault is detected. The 2 data bytes are in DIRECT format. In response to the OT_FAULT_LIMIT being
exceeded, the device does the following:
1) Sets the TEMPERATURE bit in STATUS_BYTE.
2) Sets the TEMPERATURE and MFR bits in STATUS_WORD.
3) Sets the OT_FAULT bit in STATUS_MFR_SPECIFIC.
4) Responds as specified in MFR_FAULT_RESPONSE.
5) Notifies the host using ALERT assertion (if enabled in MFR_MODE).
