26.5.4.7 8-bit NAND Flash with NFD0_ON_D16 = 1
Hardware Configuration
Software Configuration
The following configuration has to be performed:
 Set NFD0_ON_D16 = 1 in the EBI Chip Select Assignment Register in the Bus Matrix.
 Assign the EBI CS3 to the NAND Flash by setting the bit EBI_CS3A in the EBI Chip Select Assignment Register
 Reserve A21 / A22 for ALE / CLE functions. Address and Command Latches are controlled respectively by setting
to 1 the address bit A21 and A22 during accesses.
 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 Flash timings, the
data bus width and the system bus frequency.
