FUNCTION
Indicates the device is an ISL9217. This bit is set in hardware and cannot be changed.
Indicates the device is an ISL9216. This bit is set in hardware and cannot be changed.
Reserved for ISL9208 devices.
This bit is set and reset by hardware.

This bit is set to “1” when the external thermistor indicates an over-temperature condition. If the temperature condition
has cleared, this bit is reset when the register is read.
This bit is set to “1” when the internal thermistor indicates an over-temperature condition. If the temperature condition
has cleared, this bit is reset when the register is read.
When the function is enabled, this bit is set to “1” by hardware when a discharge overcurrent or short circuit condition
occurs and the load remains heavy. When the load fail condition is cleared or under a light load, the bit is reset when the
register is read.
This bit is set by hardware when a short circuit condition occurs during discharge. When the discharge short circuit
condition is removed, the bit is reset when the register is read.
This bit is set by hardware when an overcurrent condition occurs during discharge. When the discharge overcurrent
condition is removed, the bit is reset when the register is read.
This bit is set by hardware when an overcurrent condition occurs during charge. When the charge overcurrent condition
is removed, the bit is reset when the register is read.
’WKUP’ HIGH = WKUP pin > Threshold voltage
‘WKUP’ LOW = WKUP pin < Threshold voltage
’WKUP’ HIGH = WKUP pin < Threshold voltage
‘WKUP’ LOW = WKUP pin > Threshold voltage
