External Boot — This input is tied to V
boot from off-chip memory (assuming that the on-chip Flash
memory is not in a secure state). Otherwise, it is tied to ground.
For details, see
Note: When this pin is tied low, the customer boot software
should disable the internal pull-up resistor by setting the XBOOT
bit of the SIM_PUDR; see

External Memory Mode — This device will boot from internal
Flash memory under normal operation.
This function is also affected by EXTBOOT and the Flash
security mode; see
