Software Configuration
The following configuration has to be performed:
• Assign the EBI CS4 and/or EBI_CS5 to the CompactFlash Slot 0 or/and Slot 1 by setting the
• The address line A23 is to select I/O (A23=1) or Memory mode (A23=0) and the address line
• A23, CFRNW, CFS0, CFCS1, CFCE1 and CFCE2 signals are multiplexed with PIO lines and
• Configure a PIO line as an output for CFRST and two others as an input for CFIRQ and
• Configure SMC CS4 and/or SMC_CS5 (for Slot 0 or 1) Setup, Pulse, Cycle and Mode
bit EBI_CS4A or/and EBI_CS5A in the EBI Chip Select Assignment Register located in the
bus matrix memory space.
