SDIO Simplified Specification Version 2.00

6.10Function Basic Registers (FBR)

In addition to the CCCR, each supported I/O function has a 256-byte area used to allow the host to quickly determine the abilities and requirements of each function, enable power selection for each function and to enable software loading. The address of this area is from 0x00n00 to 0x00nFF where n is the function number

(0x1 to 0x7). This per-function area is structured as follows:

Description

The SDIO Standard Function code identifies those I/O functions, which implement the recommended standard interface as defined in a separate Application Specification. A complete and current list of assigned standard codes shall be maintained and published in any addendums to this specification. The codes assigned to those standard interfaces at the time this specification was published are:

0x0 No SDIO standard interface supported by this function

0x1 This function supports the SDIO Standard UART

0x2 This function supports the SDIO Type-A for Bluetooth standard interface

0x3 This function supports the SDIO Type-B for Bluetooth standard interface 0x4 This function supports the SDIO GPS standard interface

0x5 This function supports the SDIO Camera standard interface

0x6 This function supports the SDIO PHS standard interface

0x7 This function supports the SDIO WLAN interface

0x8 This function supports the Embedded SDIO-ATA standard interface (Embedded SDIO-ATA shall be implemented only on devices following the “Embedded SDIO Specification”).

0x9-0x0E Not assigned, reserved for future use

0xF This function supports an SDIO standard interface number greater than 0xE. In this case, the value in byte 0x101 identifies the standard SDIO interfaces type.

If this function supports and contains a Code Storage Area (CSA), this bit shall be set to 1. If this function does not support a CSA, this bit shall be cleared to 0. CSA enable is controlled by bit 7 of register 0xn00.
