4 EXTERNAL BUS INTERFACE
UNIT MODULE
This chapter describes the external bus interface unit (EBIU) module. The
EBIU enables the configuration of the asynchronous memory controller
and the SDRAM or DDR interface. It also allows the DDR or SDRAM to
be automatically adjusted in response to changes in the system clock
frequency.
