TS8G~16GCF600

600X CompactFlash Card

 

 

 

CompactFlash Storage Cards supporting DMA modes 1 and above. If bit 1 of word 53 is set to one, but this field is not supported, the Card shall return a value of zero in this field.

￿Recommended Multiword DMA transfer cycle time

Word 66 of the parameter information of the Identify Device command is defined as the recommended Multiword DMA transfer cycle time. This field defines, in nanoseconds, the cycle time that, if used by the host, may optimize the data transfer from by reducing the probability that the CompactFlash Storage Card will need to negate the DMARQ signal during the transfer of a sector.

If this field is supported, bit 1 of word 53 shall be set to one. The value in word 66 shall not be less than the value in word 65. This field shall be supported by all CompactFlash Storage Cards supporting DMA modes 1 and above. If bit 1 of word 53 is set to one, but this field is not supported, the Card shall return a value of zero in this field.

￿Word 67: Minimum PIO transfer cycle time without flow control

Word 67 of the parameter information of the Identify Device command is defined as the minimum PIO transfer without flow control cycle time. This field defines, in nanoseconds, the minimum cycle time that, if used by the host, the CompactFlash Storage Card guarantees data integrity during the transfer without utilization of flow control. If this field is supported, Bit 1 of word 53 shall be set to one. Any CompactFlash Storage Card that supports PIO mode 3 or above shall support this field, and the value in word 67 shall not be less than the value reported in word 68. If bit 1 of word 53 is set to one because a CompactFlash Storage Card supports a field in words 64-70 other than this field and the CompactFlash Storage Card does not support this field, the CompactFlash Storage Card shall return a value of zero in this field.

￿Word 68: Minimum PIO transfer cycle time with IORDY

Word 68 of the parameter information of the Identify Device command is defined as the minimum PIO transfer with IORDY flow control cycle time. This field defines, in nanoseconds, the minimum cycle time that the CompactFlash Storage Card supports while performing data transfers while utilizing IORDY flow control. If this field is supported, Bit 1 of word 53 shall be set to one. Any CompactFlash Storage Card that supports PIO mode 3 or above shall support this field, and the value in word 68 shall be the fastest defined PIO mode supported by the CompactFlash Storage Card. If bit 1 of word 53 is set to one because a CompactFlash Storage Card supports a field in words 64-70 other than this field and the CompactFlash Storage Card does not support this field, the CompactFlash Storage Card shall return a value of zero in this field.

￿Words 82-84: Features/command sets supported

Words 82, 83, and 84 shall indicate features/command sets supported. The value 0000h or FFFFh was placed in each of these words by CompactFlash Storage Cards prior to ATA-3 and shall be interpreted by the host as meaning that features/command sets supported are not indicated. Bits 1 through 13 of word 83 and bits 0 through 13 of word 84 are reserved. Bit 14 of word 83 and word 84 shall be set to one and bit 15 of word 83 and word 84 shall be cleared to zero to provide indication that the features/command sets supported words are valid. The values in these words should not be depended on by host implementers.

Bit 0 of word 82 shall be set to zero; the SMART feature set is not supported. If bit 1 of word 82 is set to one, the Security Mode feature set is supported.

Bit 2 of word 82 shall be set to zero; the Removable Media feature set is not supported. Bit 3 of word 82 shall be set to one; the Power Management feature set is supported. Bit 4 of word 82 shall be set to zero; the Packet Command feature set is not supported. If bit 5 of word 82 is set to one, write cache is supported.

If bit 6 of word 82 is set to one, look-ahead is supported.

Bit 7 of word 82 shall be set to zero; release interrupt is not supported. Bit 8 of word 82 shall be set to zero; Service interrupt is not supported.

Bit 9 of word 82 shall be set to zero; the Device Reset command is not supported.

Bit 10 of word 82 shall be set to zero; the Host Protected Area feature set is not supported. Bit 11 of word 82 is obsolete.

Bit 12 of word 82 shall be set to one; the CompactFlash Storage Card supports the Write Buffer command. Bit 13 of word 82 shall be set to one; the CompactFlash Storage Card supports the Read Buffer command.
