RESET

Schmitt
Input
Input
Reset
— This input is a direct hardware reset on the
processor. When RESET is asserted low, the device is
initialized and placed in the reset state. A Schmitt trigger
input is used for noise immunity. When the RESET pin is
deasserted, the initial chip operating mode is latched from
the EXTBOOT pin. The internal reset signal will be
deasserted synchronous with the internal clocks after a
fixed number of internal clocks.
To ensure complete hardware reset, RESET and TRST
should be asserted together. The only exception occurs in
a debugging environment when a hardware device reset is
required and the JTAG/EOnCE module must not be reset.
In this case, assert RESET but do not assert TRST.
Note:
The internal Power-On Reset will assert on initial
power-up.
To deactivate the internal pull-up resistor, set the RESET
bit in the SIM_PUDR register. See
Section 6.5.6
for
details.

Reset Output
— This output reflects the internal reset
state of the chip.
EXTBOOT

Schmitt
Input
Input
External Boot
— This input is tied to V
DD
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
Input
External Memory Mode
— This input is tied to V
DD
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
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
.
