In order to use this module, other parts of the system must be configured correctly, as described
below.
The SDRAMC module signals pass through the External Bus Interface (EBI) module where they
are multiplexed. The user must first configure the I/O controller to assign the EBI pins corre-
sponding to SDRAMC signals to their peripheral function. If I/O lines of the EBI corresponding to
SDRAMC signals are not used by the application, they can be used for other purposes by the
I/O Controller.
