The timing diagram for True IDE DMA mode of operation in this section is drawn using the conventions in the
ATA-4 specification, which are different than the conventions used in the PCMCIA specification. Signals are shown
with their asserted state as high regardless of whether the signal is actually negative or positive true. Consequently,
the –IORD, the –IOWR, and the –IOCS16 signals are shown in the diagram inverted from their electrical states on
the bus.

Notes:
1) t
the minimum command recovery time or command inactive time for input and output cycles
respectively. The actual cycle time equals the sum of the actual command active time and the actual
command inactive time. The three timing requirements of t
minimum total cycle time requirement is greater than the sum of t
cycles respectively. This means a host implementation can lengthen either or both of t
t
identify drive data. A CompactFlash Card implementation shall support any legal host implementation.
