TPS6594-Q1: After power-on, there is no power output, and the output must be written to the enable control output register

The power supply scheme adopts the TPS6594-Q1 scheme, that is, the combination of TPS65941213+TPS65941211.

1.After the first power-on, the TPS65941213 and TPS65941211 have no power output. The register value is obtained after the register is read:

All power supplies have been shut down.

Based on the documentation I've read, I talked to the techs. After the chip is powered on, it should be the default output, and it is not necessary to write the control register again to enable the output.

Is there anything wrong with my situation? Is there output by default after power-on?

2.If the TPS6594 needs to write the register to control the output after power-on, then it is only necessary to write once for the first time on the power-on, and the chip can automatically save the latest write state?

3.I found on the site with TPS6594 debugging using the web interface, dev.ti.com/.../, do we have the corresponding debugging interface debugging line to use?
