Bus Operation
20.6.1
CSBRn[EBI] is 00 for FLASH/SRAM devices and peripherals having 16- or 32-bit data bus widths. These
memory devices have separate pins for independent byte strobes, write enable, chip select, and output
enable. All chip selects support this EBI mode.
The number of wait states required for the external memory or peripheral is programmed through
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. When TA is used to terminate
the bus cycle, the bus cycle will have a minimum of one wait states. Additional wait states can be added
by delaying the assertion of TA.
