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.

◆ neorv32_slink_get_rx_fifo_depth()

int neorv32_slink_get_rx_fifo_depth ( void )

Get FIFO depth of RX link.

Returns: FIFO depth of RX link.

◆ 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.

◆ neorv32_slink_rx_empty()

int neorv32_slink_rx_empty ( void )

Check if RX FIFO is empty.

Returns: Zero if RX FIFO is not empty, non-zero if RX FIFO is empty.

◆ neorv32_slink_rx_full()

int neorv32_slink_rx_full ( void )

Check if RX FIFO is full.

Returns: Zero if RX FIFO is not full, non-zero if RX FIFO is full.

◆ neorv32_slink_setup()

void neorv32_slink_setup ( uint32_t irq_mask )

Reset, enable and configure SLINK.

Parameters

[in] irq_mask Interrupt conditions (NEORV32_SLINK_CTRL_enum).

◆ neorv32_slink_tx_empty()

int neorv32_slink_tx_empty ( void )

Check if TX FIFO is empty.

Returns: Zero if RX FIFO is not empty, non-zero if RX FIFO is empty.

◆ neorv32_slink_tx_full()

int neorv32_slink_tx_full ( void )

Check if TX FIFO is full.

Returns: Zero if TX FIFO is not full, non-zero if TX FIFO is full.
