ARM CM940T 3.5Reset controller

Hardware Description

3.5Reset controller

The core module FPGA incorporates a reset controller which enables the core module to be reset as a standalone unit or as part of an Integrator development system. The core module can be reset from five sources:

•reset button

•motherboard

•other core modules

•Multi-ICE

•software.

Figure 3-3shows the architecture of the reset controller.
