I checked the end addrss is marked as 2**H_ADDR_WIDTH but nowhere have it documented.

Please provide me your project name with community message, I will check it internally.

Thanks

Hello,

My project name is Data Logger, for which SD card is being interfaced to LPC54608 microcontroller. While in the development, we got a doubt how much is the size of SDIO FIFO. So that we can know whether DMA is necessary or not for transfer of data. 

Regards,

Muralidhar

Here, Buffer size is 32 * 32 = 1024 bits = 128 bytes

Have a nice day,
