BQ25882: About Masked Flag register

Hi tiers.

I set REG13 Register (Charger Mask 2 Register) as below.

Reg[0x13] = 0x87.

So, PG_MASK (power good INT Mask) is masked.

But When power source is inserted, PG_FLAG (power good INT flag) is still 1 (detected) as below.

Reg[0x10] = 0x82. (After read, set by 0)

Is this right operation?

Does the INT Mask Register relate only to the HW INT output pulse and not to the Flag Register?

Please let me know ASAP.

Thanks.
