Size of the CSA space available for this function in bytes

This byte contains flags identifying properties of this function’s CSA. The bits are defined in Table 16-11

This is both the maximum block size and byte count that this function can support. A value of zero is not valid and shall not be used.

This is the OCR value for this function. The format is identical to the 32-bit OCR format used by SD memory devices. For more details, see section 5.1 of the SD Physical Specification.

This is the minimum current, in mA, required by this function when operating. This value is valid for all voltages supported by this function. If the required current exceeds 200mA, this value shall be zero.

This is the average current, in mA, required by this function when operating. This value is valid for all voltages supported by this function. If the required current exceeds 200mA, this value shall be zero

This is the maximum (peak) current, in mA, required by this function when operating. This value is valid for all voltages supported by this function. If the required current exceeds 200mA, this value shall be zero

This is the minimum current, in mA, required by this function when in the standby condition. If this function does not support standby, this value shall be 0x00. The method to place this function in the standby state and the capabilities it has while in standby are vendor defined. This value is valid for all voltages supported by this function. Note that this value is valid only for standard power SDIO cards or high-power cards when EMPC is 0. With an 8-bit field, the range is from 0 to 254 mA. A value of 255 (0xFF) is used to indicate a value of 255mA or greater.

A value of 255 (0xFF) is used to indicate a value of 255mA or greater.

This is the minimum data transfer bandwidth, in KB/sec, needed by this function to successfully operate. If this function has no minimum necessary bandwidth, these bytes shall be 0x0000.

This is the data transfer bandwidth, in KB/sec, needed by this function to function at an optimum level. If this function has no optimum bandwidth, these bytes shall be 0x0000.

(Added in SDIO Rev 1.1) This 16-bit value indicates the function’s required time-out value for coming ready after being enabled. This per-function value indicates the time a host should wait from asserting IOEx until expecting the card to indicate ready by asserting IORx. Different SDIO functions take different amounts of time to become ready after being enabled due to different internal initialization requirements. The required time-out limit is in 10mS steps, allowing a range of 0-655.35
