This piece of code sets the bit manually.

I don't know if there also is a specific function/macro to change the bit.

# include "altera_avalon_dma_regs.h"

int reg;

reg = IORD_ALTERA_AVALON_DMA_CONTROL (dma_base_address);

IOWR_ALTERA_AVALON_DMA_CONTROL (dma_base_address, reg | ALTERA_AVALON_DMA_CONTROL_RCON_MSK);
