Function Documentation

neorv32_slink_available()

int neorv32_slink_available

(

void

)

Check if stream link interface was synthesized.

Returns

Zero if SLINK was not synthesized, non-zero if SLINK is available.

int neorv32_slink_get_rx_fifo_depth

(

void

)

Get FIFO depth of RX link.

Returns

FIFO depth of RX link (number of entries).

neorv32_slink_get_tx_fifo_depth()

int neorv32_slink_get_tx_fifo_depth

(

void

)

Get FIFO depth of TX link.

Returns

FIFO depth of TX link (number of entries).

neorv32_slink_setup()

void neorv32_slink_setup	(	int	rx_irq_sel,
		int	tx_irq_sel )

Reset, enable and configure SLINK.

Parameters

[in]	rx_irq_sel	RX interrupt condition (NEORV32_SLINK_RX_IRQ_enum).
[in]	tx_irq_sel	TX interrupt condition (NEORV32_SLINK_TX_IRQ_enum).
