Avalon SPI Interface: Bus width?

when using the SPI avalon interface function "alt_avalon_spi_command", it supports only 8bit bus width. Is there another way (function) to send also 16bit? Thanks!

Hi Hugo,

You could write your own version of the spi_read / spi_write functions using IORD and IOWR directly. The Embedded Peripherals IP User Guide is a good reference on how to do that manually

Cheers,
