→Note on boot signals:
=== Note on boot signals: ===
* BOOT_MODE_SEL is latched when processor reset is released. Inside the SOM, BOOT_MODE_SEL is pulled-up with 10 kohm.
* The iMX93x SoC uses some GPIOs to read the boot configuration set on the SOM: for this reason the SOM's ports UART1_TXD, UART2_TXD, SAI1_TXFS and SAI1_TXD0 are floating (high impedance) while CPU_PORn signal is low.
