SDIO Simplified Specification Version 2.00

Note 1: the use of CISTPL_SDIO_STD is mandatory for all functions that claim to support a SDIO standard interface specification (see 1.3). If the function does not support a standard SDIO interface, this tuple should be used with a value of 0.

16.6CISTPL_MANFID: Manufacturer Identification String Tuple

The manufacturer identification tuple contains information about the manufacturer of a SDIO Card. Two types of information are provided: the SDIO Card's manufacturer and a manufacturer card number. This tuple shall be present in the card common CIS.

This should also be present in each function’s CIS. This allows a function to override the card common manufacturer information so the driver can take advantage of unique features.

Byte	7		6		5	4	3	2	1	0
0x00					TPL_	CODE CISTPL_MANFID (20H)
0x01					TPL_LINK Link to next tuple (at least 4)
0x02-0x03				TPLMID_MANF SDIO Card manufacturer code
0x04-0x05		TPLMID_CARD manufacturer information (Part Number and/or Revision)

Table 16-3 CISTPL_MANFID: Manufacturer Identification Tuple

The TPLMID_MANF field identifies the SDIO Card's manufacturer. New codes are assigned by both PCMCIA and JEIDA. The first 256 identifiers (0x0000 through 0x00FF) are reserved for manufacturers who have JEDEC IDs assigned by JEDEC Publication 106. Manufacturers with JEDEC IDs may use their eight-bit JEDEC manufacturer code as the least significant eight bits of their SDIO Card manufacturer code. In this case, the most significant eight bits shall be zero (0). For example, if a JEDEC manufacturer code is 89H, their SDIO Card manufacturer code is 0x0089. If a SDIO card manufacturer does not currently have a TPLMID_MANF assigned, one can be obtained at little or no cost from the PCMCIA. The TPLMID_CARD field is reserved for the use of the SDIO Card's manufacturer. It is anticipated that the field will be used to store card identifier and revision information.

16.7SDIO Specific Extensions

SDIO cards use two to four tuples to provide additional information about the card (common) and each function. The first is the Function ID tuple. The changes for SDIO are detailed in the next sections.

16.7.1CISTPL_FUNCID: Function Identification Tuple

To identify an SDIO card, the CISTPL_FUNCID tuple shall exist in all CIS areas. This means there shall be a CISTPL_FUNCID in the common CIS space chain and one in each function’s CIS space chain. The format of this tuple is shown in

Byte	7		6		5	4	3	2	1	0
0x00					TPL_	CODE CISTPL_FUNCID (0x21)
0x01					TPL_LINK Link to next tuple (0x02)
0x02				TPLFID_FUNCTION Card function code (0x0C)
0x03		TPLFID_SYSINIT System initialization bit mask. (Not used, set to 0x00)

Table 16-4 CISTPL_FUNCID Tuple

The function identification tuple contains information about the functionality provided by an SDIO Card. Information is also provided to enable system utilities to decide if the SDIO Card should be configured during system initialization. Since additional function specific information is available, one or more function extension tuples follow this tuple. The TPLFID_FUNCTION field contains an identifier assigned by PCMCIA (0x0C) to identify the SDIO device class.
