Application Example
Shared CompactFlash Interface Multiplexing
Figure 19-5 on page 148
CFRNW signals are not directly connected to the CompactFlash slot 0, but do control the direc-
tion and the output enable of the buffers between the EBI and the CompactFlash Device. The
timing of the CFCS0 signal is identical to the NCS4 signal. Moreover, the CFRNW signal
remains valid throughout the transfer, as does the address bus. The CompactFlash _WAIT sig-
nal is connected to the NWAIT input of the Static Memory Controller. For details on these
waveforms and timings, refer to the section “Static Memory Controller (SMC)”.
