DS90UB954-Q1: Write UB953 reg addr 0x01 failed after init UB954 and read DEVICE_STS is 0xDF

Hi TI team

I found an issue for accessing UB953 failed.

The reproduced rate is about 1%.

Before that, I init UB954 successfully,

and then read DEVICE_STS(Address 0x04) is 0xDF (that means device LOCK and PASS status),

and then wait 300ms.

Could you kindly help to analysis this issue?

I think accessing UB953 will be successful after read DEVICE_STS LOCK and PASS status.
