State of GPIOs on power up

Hi,

 

I am designing a board that utilizes the LS1046 processor. I need to control a signal and make sure it is defined after power up before booting up the device.

 

Is there a defined state for the GPIOs on the LS1046 processor?

 

Thanks!

After power up the processor goes through power-on reset where it reads RCW and configures pins as per RCW setup. All pins configured as GPIO are put into 'input' state, this means they are in high-z state.
