BQ40Z80: FET protection

Part Number: BQ40Z80

in section 12.1 of the TRM, on p85, it says:

In a series-circuit configuration, if the CHG FET is off and the DSG FET is on, then if discharge current
greater than Charge Current Threshold is detected, the CHG FET is turned on quickly to protect the
CHG FET body diode from discharge current flowing through it. If the FETs are configured in series,
select FET Options[PARALLEL_FETS] = 0. 

Does this behaviour occur in test mode when FET_EN = 0 and the discharge FET is toggled on in test mode, or is it only available when FET_EN = 1?
