SDMMC IDMA buffer size register
IDMABNDT | Number of bytes per buffer This 12-bit value must be multiplied by 8 to get the size of the buffer in 32-bit words and by 32 to get the size of the buffer in bytes. Example: IDMABNDT = 0x001: buffer size = 8 words = 32 bytes. Example: IDMABNDT = 0x800: buffer size = 16384 words = 64 Kbyte. These bits can only be written by firmware when DPSM is inactive (DPSMACT = 0). |
