External Boot — This input is tied to V
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
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 input is tied to V
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
