I need to control an AD5663 with a BF547's SPI bus. I have seen in the Hardware Reference manual and also the adi_spi_int that this spi bus can send words sizes of either 8 or 16 bits. I have seen this reflected in the ADI_SPI_CMD_SET_WORD_SIZE command where the documentation states this can be set to 8 or 16. Trouble is an SPI bus command to the AD5663 needs 24 bits. Can the BF547's SPI bus control an AD5663?
