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 — The EMI_MODE input is internally tied
low (to V
under normal operation. This function is also affected by
EXTBOOT and the Flash security mode. For details, see
Table
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
