•

SD 1-Bit Mode

•

SD 4-Bit Mode

•

Low Speed

•

Full Speed (25 MHz)

•

Interrupt

•

CMD52 during Data Transfer

•

CMD53 Multi Block Transfer

Interrupt during 4-bit Multiple Block Data Transfer

•

Combo Card (I/O mode only)

4.1.2

SDIO Function 0/1

For Function 0 registers descriptions, refer to SDIO Card Specification. For Function 1, the SDIO registers

occupy a 128 Kbyte space as defined in the SDIO specification. Figure 2 illustrates SDIO Function 1

128 Kbyte Memory Map and Table 8 details its registers.
