Hardware Configuration
Software Configuration
The following configuration has to be performed:
• Assign the EBI CS4 to the CompactFlash slot by setting the bit EBI_CS4A in the EBI Chip
• The address line A23 is to select I/O (A23=1) or Memory mode (A23=0) and the address line
• A23, CFRNW, CFCS0, CFCE1 and CFCE2 signals are multiplexed with PIO lines and thus
• Configure a PIO line as an output for CFRST and two others as an input for CFIRQ and
• Configure SMC CS4 Setup, Pulse, Cycle and Mode accordingly to Compact Flash timings
Select Assignment Register located in the Bus Matrix memory space.
