266X CompactFlash Card

 

 

 

¾Translation Parameters Valid

Bit 0 shall be set to 1 indicating that words 54 to 58 are valid and reflect the current number of cylinders, heads and sectors. If bit 1 of word 53 is set to 1, the values in words 64 through 70 are valid. If this bit is cleared to 0, the values reported in words 64-70 are not valid. Any CompactFlash Storage Card that supports PIO mode 3 or above shall set bit 1 of word 53 to one and support the fields contained in words 64 through 70.

¾Current Number of Cylinders, Heads, Sectors/Track

These fields contains the current number of user addressable Cylinders, Heads, and Sectors/Track in the current translation mode.

¾Current Capacity

This field contains the product of the current cylinders times heads times sectors.

¾Multiple Sector Setting

Bits 15-9 are reserved and shall be set to 0.

Bit 8 shall be set to 1 indicating that the Multiple Sector Setting is valid.

Bits 7-0 are the current setting for the number of sectors that shall be transferred per interrupt on Read/Write Multiple commands.

¾Total Sectors Addressable in LBA Mode

This field contains the total number of user addressable sectors for the CompactFlash Storage Card in LBA mode only.

¾Multiword DMA transfer

Bits 15 through 8 of word 63 of the Identify Device parameter information is defined as the Multiword DMA mode selected field. If this field is supported, bit 1 of word 53 shall be set to one. This field is bit significant. Only one of bits may be set to one in this field by the CompactFlash Storage Card to indicate the multiword DMA mode which is currently selected. Of these bits, bits 15 through 11 are reserved. Bit 8, if set to one, indicates that Multiword DMA mode 0 has been selected. Bit 9, if set to one, indicates that Multiword DMA mode 1 has been selected. Bit 10, if set to one, indicates that Multiword DMA mode 2 has been selected.

Selection of Multiword DMA modes 3 and above are specific to CompactFlash are reported in word 163, Word 163: CF Advanced True IDE Timing Mode Capabilities and Settings.

Bits 7 through 0 of word 63 of the Identify Device parameter information is defined as the Multiword DMA data transfer supported field. If this field is supported, bit 1 of word 53 shall be set to one. This field is bit significant. Any number of bits may be set to one in this field by the CompactFlash Storage Card to indicate the Multiword DMA modes it is capable of supporting.

Of these bits, bits 7 through 2 are reserved. Bit 0, if set to one, indicates that the CompactFlash Storage Card supports Multiword DMA mode 0. Bit 1, if set to one, indicates that the CompactFlash Storage Card supports Multiword DMA modes 1 and 0. Bit 2, if set to one, indicates that the CompactFlash Storage Card supports Multiword DMA modes 2, 1 and 0. Support for Multiword DMA modes 3 and above are specific to CompactFlash are reported in word 163, Word 163: CF Advanced True IDE Timing Mode Capabilities and Settings.

¾Word 64: Advanced PIO transfer modes supported

Bits 7 through 0 of word 64 of the Identify Device parameter information is defined as the advanced PIO data transfer supported field. If this field is supported, bit 1 of word 53 shall be set to one. This field is bit significant. Any number of bits may be set to one in this field by the CompactFlash Storage Card to indicate the advanced PIO modes it is capable of supporting.
