signals are not directly connected to the CompactFlash slot, but do control the direction and the
output enable of the buffers between the EBI and the CompactFlash Device. The timing of the
CFCS signal is identical to the NCS4 signal. Moreover, the CFRNW signal remains valid
throughout the transfer, as does the address bus. The CompactFlash _WAIT signal is con-
nected to the NWAIT input of the Static Memory Controller. For details on these waveforms and
timings, refer to the Static Memory Controller
