*'''BOOTMODE''' is used to setup a boot priority sequence. BOOTMODE is equal to #SYS_BOOT4. It and it has a 100K PU signalresistor.

* It is recommendable add a jumper header (or switch) series with a 100 Ohms 100R resistor tied to GND in your base board to manage boot priority sequence. For example: If you want to reflash the internal NAND memory from microSD card you will need to unmount the jumper.* Read the resources detailed above to get more More informationat [{{#lst:Template:Links|IGEP_AQUILA_EXPANSION_ISEE_Hardware}} IGEP AQUILA EXPANSION Hardware Reference Manual] section 6.1 and [{{#lst:Template:Links|IGEP_AQUILA_EXPANSION_ISEE_Hardware}} IGEP AQUILA EXPANSION Hardware Reference Manual] section 5.8.
