Freescale Semiconductor
There is a special timing requirement in the ATA host that requires the internal DIOW to go only high 3 clocks after the last
active edge on the DSTROBE signal. The equation given on this line tries to capture this constraint.
Make ton and toff big enough to avoid bus contention.
