When exactly are the BT_CFG pins sampled?

I know that BOOT_MODE are sampled on rising edge of POR_B, but cannot find info regarding the BT_CFG overides.

Thanks to anyone who can help me with this.

Hello David Wende,

This information is indeed not available on the documentation but the boot configuration pins should be read on the next clock rising edge to continue booting. It is the next step on the booting process after the boot mode, so there is no much delay between the boot mode being read and the boot configuration pins being sampled (when obtaining the boot configuration from them).

I hope this helps!

Regards,
