Word 65: minimum multi-word DMA transfer cycle time
Word 65 of the parameter information of the Identify Device command is defined as the
minimum multi-word DMA transfer cycle time.
It corresponds to the minimum cycle time for which the card ensures data integrity during
transfers. It is expressed in nanoseconds.
The returned value is ‘50h’ (for cycle time values refer to
Word 66: recommended multi-word DMA transfer cycle time
Word 66 of the parameter information of the Identify Device command is defined as the
recommended multi-word DMA transfer cycle time. The returned value is ‘50h’ (for cycle
time values refer to
Word 67: minimum PIO transfer cycle time without flow control
This field gives the minimum cycle time (in ns) that the host should use for the
CompactFlash memory card to ensure data integrity during transfers when flow control is
not used. The returned value is ‘50h’ (for cycle time values refer to
Word 68: minimum PIO transfer cycle time with IORDY
This field gives the minimum cycle time (in ns) supported by the CompactFlash memory
card to perform data transfers using IORDY flow control. The returned value is ‘50h’ (for
cycle time values refer to
Word 163: advanced true IDE timing mode capabilities and settings
This word describes the capabilities and current settings for CFA defined advanced timing
modes using the true IDE interface.
There are four sub-fields that describe the advanced PIO and advanced multi-word DMA
timing modes supported and selected:
Bits 2-0: advanced true IDE PIO mode supported.
The returned value is ‘2h’ to indicate that PIO mode 6 is the highest PIO mode
supported
Bits 5-3: advanced true IDE multi-word DMA mode supported.
The returned value is ‘2h’ to indicate that multi-word DMA mode 4 is the highest multi-
word DMA mode supported.
Bits 8-6: advanced true IDE PIO mode selected.
These bits indicate the current true IDE PIO mode selected on the card.
Bits 11-9: advanced true IDE multi-word DMA mode selected.
These bits indicate the current true IDE multi-word DMA mode selected on the card.
