Byte-Wide Multi-Device AP Configuration
The simpler method for multi-device AP configuration is the byte-wide multi-device
AP configuration. In the byte-wide multi-device AP configuration, the LSB of the
DATA[7..0]pin from the flash and master device (set to the AP configuration
scheme) is connected to the slave devices set to the FPP configuration scheme, as
shown in
