This device driver controls SD cards with the use of the on-chip SD host interface (SDHI) of an MCU. Using this driver along with a lower-layer SDHI FIT module allows you to control SD memory and SDIO (Secure Digital Input/Output).
You can update or read data by simply calling user API functions. This device driver is a Firmware Integration Technology (FIT) module which supports FIT. In combination with other FIT modules, you can easily include various sample code in user applications. DMAC or DTC transfer can be included by combining the SD card driver with the DMAC FIT module or DTC FIT module.
- Bus Interface
Support is only for 4-bit SD mode.
- Numbers controllable
- Speed mode
Supports default speed mode.
- Transfer of data in the MCU
You can choose transfer by software, DMA, or the DTC.
- MCU-dependent part
Divided out in the SDHI FIT module.
- Memory Capacity
Supports standard-capacity SD memory cards (SDSC) and high-capacity and extended-capacity SD memory cards (SDHC and SDXC).
- Target for memory control
Support is only for user areas.
