BQ40Z50-R1: BQ40Z50 default security modes

Hello Hao,

The default should be Full Access mode when the device is first turned on.

The easiest way to change the security mode is to click on the UNSEAL and UNSEAL_FULL_ACCESS buttons under Commands.

This e2e post includes a good example on how to do it with the Advanced Comm: https://e2e.ti.com/support/power-management/f/power-management-forum/664067/bq40z50-r2-unseal-the-device 

Best,
