TPS23880: When open circuit, can't read the status from Reg CHANNEL 1 DISCOVERY

Part Number:TPS23880

Hi,

When testing TPS23880 with Reg 0x29 as value 0x0F (4 pair 90W), our got detection result from Reg 0x0C as value 0x0B/0x0C/0x0D/0x0F which are not listed in Table 12 of datasheet.

But result is what we expected when test TPS23880 with Reg 0x29 as value 0x03 (2 pair 30W) or using TPS23880EVM

1. Could you please tell us what the values(0x0B/0x0C/0x0D/0x0F) stand for?

2. How and why we got these values?

Or anything needs to be provided?

Thank you,

C.T.
