CC3220MODA: Timely configuration of GPIO lines at boot

Part Number: CC3220MODA

Hi

Our board uses a CC3220MODASF within a power controller which requires me to assert a GPIO line within 1 second of power-up to hold power on. Tests indicate boot time before the application gets control is around 1.5 s, by the time the device (referring to swru465 Feb 2017 section 21.6, this seems plausible). Is there any way to configure at least some GPIO lines earlier on in the boot process? I can deal with unconfigured lines during initial programming, but thereafter, in the field, need to be able to do this.

Thanks

Tim
