BQ25150EVM: Flags/bits are not update from STATUS Registers

Part Number: BQ25150EVM

Hi,

1. Currently I am using BQ25150 TI EVM, but don't have battery.

2. Connected /CE pin to ground.

I want to do charging ON/OFF by I2C ICCTRL2(-> bit 0th) register.

When i write 0 on ICCTRL2 (-> bit 0th) then write operation is successful, but CHRG_CV_STAT bit from STAT0 register not set(active).

& same for setting Current limit to 100 mA, IINLIM_ACTIVE_STAT bit from STAT0 register not set (active).

why ??

I want to cross check of my operation by reading status register.

Is there any battery dependency ??, or other way to do that ??

Thanks & Regards
