7.8 Host Configuration Requirements for Master/Slave or New Timing Modes
The CF Advanced Timing modes include PCMCIA PC Card style I/O modes that are faster than the original 250 ns
cycle time. These modes are not supported by the PCMCIA PC Card specification nor CF by cards based on revisions
of the CF specification before Revision 3.0. Hosts shall ensure that all cards accessed through a common electrical
interface are capable of operation at the desired, faster than 250 ns, I/O mode before configuring the interface for
that I/O mode.
Advanced Timing modes are PCMCIA PC Card style I/O modes that are 100 ns or faster, PC Card Memory modes that
are 100ns or faster, True IDE PIO Modes 5, 6 and Multiword DMA Modes 3, 4. These modes are permitted to be used
only when a single card is present and the host and card are connected directly, without a cable exceeding 0.15m
in length. Consequently, the host shall not configure a card into an Advanced Timing Mode if two cards are
sharing I/O lines, as in Master/Slave operation, nor if it is constructed such that a cable exceeding 0.15 meters is
required to connect the host to the card.
The load presented to the Host by cards supporting Ultra DMA is more controlled than that presented by other
CompactFlash TM cards. Therefore, the use of a card that does not support Ultra DMA in a Master/Slave arrangement
with an Ultra DMA card can affect the critical timing of the Ultra DMA transfers. The host shall not configure a card
into Ultra DMA mode when a card not supporting Ultra DMA is also present on the same interface
When the use of two cards on an interface is otherwise permitted, the host may use any mode that is supported
by both cards, but to achieve maximum performance it should use its highest performance mode that is also
supported by both cards.
