seconds. If the cards required no time-out, this field shall be set to 0x0000.

This value is the same as that of TPLFE_OP_AVG_PWR. This value is the same as that of TPLFE_OP_MAX_PWR.

This 16-bit value indicates the average current, in mA, required by this function when operating in the Higher Current Mode (EMPC=1 & EPS=0). This value indicates a current range from 1 to 65535 mA.

This 16-bit value indicates the peak current, in mA, required by this function when operating in the Higher Current Mode. This value indicates a current range from 1 to 65535 mA.

This 16-bit value indicates the average current, in mA, required by this function when operating in the Lower Current Mode (EMPC=1 & EPS=1). This value indicates a current range from 1 to 65535 mA

This 16-bit value indicated the maximum (peak) current, in mA, required by this function when operating in the Lower current mode (EMPC=1 & EPS=1). This value indicates a current range from 1 to 65535 mA

FN_WUS

Table 16-10 TPLFE_FUNCTION_INFO Definition

The FN_WUS (Wake Up Support) bit signals the function’s support of wake-up when the function is placed into a low power state and the SDCLK is stopped. The intent is to allow a SDIO card to be placed into a low power condition and still signal the host of a wake-up event. If this bit is set to 1, then this function may be placed into a low power state using some function standard or vendor defined method and the SDCLK can be stopped with the power remaining applied to the card. Irrespective of the state of this bit, the host may stop the SDCLK as allowed by the SD Physical Specification.

CSA_NF

CSA_WP

Table 16-11 TPLFE_CSA_PROPERTY Definition

The CSA_WP bit is used to write protect the CSA for this function, or identifies it as read-only. If this bit is set to 1, then the CSA of this function is either write protected or read-only. If this bit is clear, then the host may write the CSA. Setting of this bit for R/W devices is handled in a vendor-defined method.

The CSA_NF bit is used to indicate to the host that the CSA area should not be reformatted. If the bit is set to 1, the host may not format the CSA file structure. If this bit is cleared to 0, then the host may reformat the file system of the CSA.
