8-bit NAND Flash
Hardware Configuration
Software Configuration
The following configuration has to be performed:
• Assign the EBI CS3 to the NAND Flash by setting the bit EBI_CS3A in the EBI Chip Select
• Reserve A21 / A22 for ALE / CLE functions. Address and Command Latches are controlled
• NANDOE and NANDWE signals are multiplexed with PIO lines and thus the dedicated PIOs
• Configure a PIO line as an input to manage the Ready/Busy signal.
• Configure Static Memory Controller CS3 Setup, Pulse, Cycle and Mode accordingly to NAND
Assignment Register located in the bus matrix memory space
respectively by setting to 1 the address bit A21 and A22 during accesses.
must be programmed in peripheral mode in the PIO controller.
