BQ40z50-r1 question for FET Option[CHGFET] and ChargingStatus()[MCHG]

Q1:
For FET Option[CHGFET] = 1, FET off is based on [FC] or [TC]?

There are two different description in TRM...

page 35
When GaugingStatus() [FC] is set AND FET Option[CHGFET] = 1, the CHG FET turns off.

page 137
CHGFET (Bit 5): FET action on setting of GaugeStatus()[TC]
1 = Charging and Precharging disabled, FET off
0 = FET active (default)

Q2:
What will ChargingStatus()[MCHG] be, 1 or 0? ChargingCurrent()=? under condition as below?
If valid charge termination,
GaugingStatus()[TC] = 1 if SOCFlagConfig B[TCASETVCT] = 1
and
GaugingStatus()[FC] = 1 if SOCFlagConfig B[FCSETVCT] = 1
and
FET Option[CHGFET] = 1

Finally, if TRM can provide  state diagram or flow chart, it will be better to understand the operation.
