27.8.5  8-bit NAND Flash with NFD0_ON_D16 = 0
27.8.5.1 Hardware Configuration
Figure 27-10. 8-bit NAND Flash with NFD0_ON_D16 = 0
27.8.5.2 Software Configuration 
The following configuration has to be performed:
Set NFD0_ON_D16 = 0 in the EBI Chip Select Assignment Register located in the bus matrix memory space
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 bits 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.
