Preliminary
EXTBOOT
124
Schmitt
Input
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 Section 6.5.6.
EMI_MODE
159
Schmitt
Input
External Memory Mode — The EMI_MODE input is
internally tied low (to VSS). This device will boot from
internal Flash memory under normal operation. This
function is also affected by EXTBOOT and the Flash
security mode. For details, see Table 4-4.
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 Section 6.5.6.
