Bus Operation
20.6.2
CSBRn[EBI] is 11 for FLASH/SRAM devices and for peripherals having 8-bit data bus widths and no byte
strobe inputs. These type of memory devices have separate pins for write enable, chip select, and output
enable. All chip selects support this EBI mode.
The key difference between EBI = 11 and EBI = 00 is that BS[3:0] can be directly connected to the R/W
inputs of the 8-bit wide SRAM devices and the R/W output from the MCF5272 can be left unconnected.
The number of wait states required for the external memory or peripheral can be programmed in
CSORn[WS]. The external transfer acknowledge signal, TA, is provided to allow off-chip control of wait
states. External control of wait states is enabled when CSORn[WS] is 0x1F.
