BQ25180: TS_Fault when holding button and charging

We've encountered an interesting case- with battery charging and button pressed for about 3 seconds we get TS_Fault  flag.

Registers:

FLAGS 0x80

STAT0 0x21

STAT1 0x00

Shouldn't the charging be suspended while the button is pressed?

And seeing how TS_STAT is all 0, is it safe to just mask TS_Fault in this case?

    Hi Igor,

    The flag may not reflect the latest so at one point, it may have been a TS fault (possibly as the voltage on TS was dropping) but it had not been cleared and so it was set once you read it. Are you continuously reading this the register? The STAT will provide the latest on the TS status. 

    Best Regards,
