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. 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
Part 6.5.6
for details.

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

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
Part 6.5.6
.
Note
: This pin is internally tied low (to V
SS
).

External Memory Mode
— This device will boot from internal
Flash memory under normal operation.
This function is also affected by EXTBOOT and the Flash security
mode; see
Table 4-4
for details.
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
.
Note:
This pin is internally tied low (to V
SS
).
