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

RESET
Input
(Schmitt)
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 it is
necessary not to reset the OnCE/JTAG module. In this case, assert
RESET, but do not assert TRST.

EXTBOOT
Input
(Schmitt)
Input
External Boot
—This input is tied to V
DD
to force device to boot from
off-chip memory. Otherwise, it is tied to VSS.
