External Boot — This input is tied to VDD to force the device
to 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 Table 4-4.
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 Part 6.5.6.

Input
Input,
pull-up
enabled
External Memory Mode — This input is tied to VDD in order
to enable an extra four address lines, for a total of 20
address lines out of reset. This function is also affected by
EXTBOOT and the Flash security mode. For details, see
If a 20-bit address bus is not desired, then this pin is tied to
ground.
Note: When this pin is tied low, the customer boot software
should disable the internal pull-up resistor by setting the
EMI_MODE bit of the SIM_PUDR; see Part 6.5.6.
