4 LP1071 Interfaces

4.1 SDIO Host Interface

The LP1071 supports SDIO Card Specifications, Version 1.00 (http://www.sdcard.org). The LP1071

SDIO host interface supports the I/O mode of the SD Card Specifications.

4.1.1 SDIO Supported Features

The features supported by the LP1071 SDIO host interface are:

• 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.
