PAGES: Page Size
TDF: Data Float Output Time
BAT: Byte Access Type
CSEN: Chip Select Enable (Code Label
EBI_CSEN
)
0 = Chip select is disabled.
1 = Chip select is enabled.
BA: Base Address (Code Label
EBI_BA
)
These bits contain the highest bits of the base address. If the page size is larger than 1M byte, the unused bits of the base
address are ignored by the EBI decoder.
