TS32M~1GCF80 80X CompactFlash Card

￿Words 7-8: Number of Sectors per Card

This field contains the number of sectors per CompactFlash Storage Card. This double word value is also the first invalid address in LBA translation mode.

￿Words 10-19: Serial Number

This field contains the serial number for this CompactFlash Storage Card and is right justified and padded with spaces (20h).

￿Word 22: ECC Count

This field defines the number of ECC bytes used on each sector in the Read and Write Long commands. This value shall be set to 0004h.

￿Words 23-26: Firmware Revision

This field contains the revision of the firmware for this product.

￿Words 27-46: Model Number

This field contains the model number for this product and is left justified and padded with spaces (20h).

￿Word 47: Read/Write Multiple Sector Count

Bits 15-8 shall be the recommended value of 80h or the permitted value of 00h. Bits 7-0 of this word define the maximum number of sectors per block that the CompactFlash Storage Card supports for Read/Write Multiple commands.

￿Word 49: Capabilities Bit 13: Standby Timer

If bit 13 is set to 1 then the Standby timer is supported as defined by the IDLE command If bit 13 is set to 0 then the Standby timer operation is defined by the vendor.

Bit 11: IORDY Supported

If bit 11 is set to 1 then this CompactFlash Storage Card supports IORDY operation.

If bit 11 is set to 0 then this CompactFlash Storage Card may support IORDY operation. Bit 10: IORDY may be disabled

Bit 10 shall be set to 0, indicating that IORDY may not be disabled. Bit 9: LBA supported

Bit 9 shall be set to 1, indicating that this CompactFlash Storage Card supports LBA mode addressing. CF devices shall support LBA addressing.

Bit 8: DMA Supported If bit 8 is set to 1 then Read DMA and Write DMA commands are supported. Bit 8 shall be set to 0. Read/Write DMA commands are not currently permitted on CF cards.

￿PIO Data Transfer Cycle Timing Mode

The PIO transfer timing for each CompactFlash Storage Card falls into modes that have unique parametric timing specifications. The value returned in Bits 15-8 shall be 00h for mode 0, 01h for mode 1, or 02h for mode 2. Values 03h through FFh are reserved.

￿Translation 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.

￿Current 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.

￿Current Capacity

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

￿Multiple 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.

￿Total Sectors Addressable in LBA Mode
