TM4C129CNCPDT: Can you terminate an already armed DMA transfer request?

I have a DMA basic mode function to transfer data from memory to the SSI transmit register. Since it is possible for the receiving device to fail, is it possible to reset the the current transfer request and allow a new request? 

The code below does not work:

void spi_slave_tx_set(uint8_t *tx, uint16_t len) {
	if (uDMAChannelModeGet(SPI_TX_DMA_CHAN | UDMA_PRI_SELECT) != UDMA_MODE_STOP)
	{
			uDMAChannelDisable(SPI_TX_DMA_CHAN);
uDMAChannelTransferSet(SPI_TX_DMA_CHAN | UDMA_PRI_SELECT, UDMA_MODE_STOP,
			&dummy, (void *)(SPI_BASE + SSI_O_DR), 0);
		
	}

	/* rearm the TX DMA */
	uDMAChannelTransferSet(SPI_TX_DMA_CHAN | UDMA_PRI_SELECT, UDMA_MODE_BASIC,
			tx, (void *)(SPI_BASE + SSI_O_DR), len);

	uDMAChannelEnable(SPI_TX_DMA_CHAN);
	SSIDMAEnable(SPI_BASE, SSI_DMA_TX);
}
