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.
According to the external devices addressed, the following table gives the clocks that should be
enabled by the Power Manager.
Table 17-2.
The EBI interface has one interrupt line connected to the Interrupt Controller:
Handling the EBI interrupt requires configuring the interrupt controller before configuring the EBI.
The EBI interface is connected to the HMATRIX Special Function Register 6 (SFR6). The user
must first write to this HMATRIX.SFR6 to configure the EBI correctly.

0 = Chip Select 1 (NCS[1]) is connected to a Static Memory device. For each
access to the NCS[1] memory space, all related pins act as SMC pins
1 = Chip Select 1 (NCS[1]) is connected to a SDRAM device. For each access
to the NCS[1] memory space, all related pins act as SDRAM pins (SDCS)
