I/O Lines
Power Management
Clocks
In order to use this module, other parts of the system must be configured correctly, as described
below.
The pins used for interfacing the compliant external devices may be multiplexed with I/O Con-
troller lines. The user must first configure the I/O Controller to assign the EBI pins to their
peripheral functions.
To prevent bus errors EBI operation must be terminated before entering sleep mode.
A number of clocks can be selected as source for the EBI. The selected clock must be enabled
by the Power Manager.
The following clock sources are available:
• CLK_EBI
• CLK_SDRAMC
• CLK_SMC
