1. t 0 is the minimum total cycle time. T D is the minimum command active time. T KR and t KW are the minimum command recovery time
or command inactive time for input and output cycles, respectively. The actual cycle time is the sum of the actual command active
time and the actual command inactive time. The timing requirements of t 0 , t D , t KR , and t KW must be respected. T 0 is higher than t D +
t KR or t D + t KW , for input and output cycles respectively. This means the host can lengthen either t D or t KR /t KW , or both, to ensure
that t 0 is equal to or higher than the value reported in the devices identify device data. A CompactFlash TM Storage Card
implementation shall support any legal host implementation.
6.5 Ultra DMA Mode
6.5.1 Ultra DMA Overview
Ultra DMA is an optional data transfer protocol used with the READ DMA, and WRITE DMA, commands. When this
protocol is enabled, the Ultra DMA protocol shall be used instead of the Multiword DMA protocol when these
commands are issued by the host. This protocol applies to the Ultra DMA data burst only. When this protocol is
used there are no changes to other elements of the ATA protocol (e.g., Command Block Register access).
Ultra DMA operations can take place in any of the three basic interface modes: PC Card Memory mode, PC Card I/O
mode, and True IDE (the original mode to support UDMA). The usage of signals in each of the modes is shown in
