BQ24079QW-Q1: BQ24079QWRGTRQ1 : SYSOFF Logic High input voltage / RC circuit implementation

Part Number: BQ24079QW-Q1
Hello TI Team,
 
We've used Battery charger IC : BQ240797QWRGTRQ1 and looking to implement Ship mode upon inserting the backup battery pack.
 
We're trying to implement a circuit around SYSOFF function that will turn off the system output with a delay through RC time constant.
 
SYSOFF is connected to MCU I/O which floats during a reset
 
One MLCC Capacitor of value 10uF : C212 is placed (Keeping C214 as a DNP) to create an RC circuit that will delay shutting down the output VOUT.
 
RC = 5MOhm internal Pull up resistors at SYSOFF pin to VBTA and C212 (capacitor - 10uF in my case ) which should slowly charge via VBAT until hits min threshold for SYSOFF (min 1.4V).
On bench level testing ,our current problem is that when probing SYSOFF we've noticed that it is shutting down way earlier than advertised Logic High which is controlled by MCU.
We've consistently measured about 700mV on TCU boards 
Even though 700mV readings on SYSOFF , but still Battery Charger Ship mode entry is done. I think SYSOFF should be logic (1.4V)  before advertising Logic high from MCU firmware.
