About device reset
This section describes the ARM9E-S reset signals and how you must use them for
correct operation of the device.
The ARM9E-S has two reset inputs:
nRESET
DBGnTRST The DBGnTRST signal is the debug logic reset that you can use to reset
Both nRESET and DBGnTRST are active LOW signals that asynchronously reset
logic in the ARM9E-S. You must take care when designing the logic to drive these reset
signals.
Copyright © 2000 ARM Limited. All rights reserved.
The nRESET signal is the main CPU reset that initializes the majority of
the ARM9E-S logic.
the ARM9E-S TAP controller and the EmbeddedICE-RT unit.
