Funcionalidades

The driver software supports clock-synchronous serial communications through GPIO port pins of an RX63N or RX631 Group MCU and controls 1-bit SD-mode SDIO devices through the sending and receiving of SD commands by controlling the RSPI port.
Notice: This driver software is exclusively for use with connected SDIO devices. That is, this driver software doesn't support SD memory cards. This software only support the SDR mode of clock timing, it does not support DDR.

 

Functions

This driver software supports Part E1, SDIO Specification, version 4.00, in version 2.00 of the SD Specifications.
