BQ40Z50-R1: PRES pin can not pull up

Part Number: BQ40Z50-R1

I want to use the PRES pin to control CHGFET and DSGFET.I set NR=0, connect the PRES pin through 100 ohm resistor to a 3.3V MCU IO. I config the MCU IO pin as push-pull mode , when I try to pull up PRES pin to turn off CHGFET and DSGFET, the PRES pin still keep low. The 100ohm resistor have 3V voltage and 10mA current ,causes the power consumption is very high.

If I config the MCU IO as open-drain mode then output high level voltage or release PRES pin ,I can’t close FET.

I find only set the NR = 1 then reset devices or keep the device in ROOM mode, I can pull up PRES pin with a normal power consumption

Where is my configuration errors?
