• PAGES: Page Size
This field defines the page size handling and the page size.
• OEL: Output Enable Latency
This field defines the number of idle cycles inserted after each level change on the BFOE output enable signal. OEL range
is 1 to 3.
• BAAEN: Burst Address Advance Enable
0: The burst clock is enabled to increment the burst address or, disabled to remain at the same address.
1: The burst clock is continuous and the burst address advance is controlled with the BFBAA pin.
• BFOEH: Burst Flash Output Enable Handling
0: No burst resume in Burst Mode. When the BFC is deselected, this causes an irreversible break of the burst. A new burst
will be initiated for the next access.
1: Burst resume. When the BFC is deselected, the burst is suspended. It will be resumed if the next access is sequential to
the last one.
• MUXEN: Multiplexed Bus Enable
0: The address and data busses operate independently.
1: The address and data busses are multiplexed. Actually, the address is presented on both the data bus and the address
bus when the BFAVD signal is asserted.
• RDYEN: Ready Enable Mode
0: The BFRDY input signal at the BFC input interface is ignored.
1: The BFRDY input signal is used as an indicator of data availability in the next cycle.
