sl_si91x_sdio_secondary_init#

sl_status_t sl_si91x_sdio_secondary_init (void )

Initializes the SDIO secondary.

By default, the SDIO pin access with TA, this API gives the pin access to M4, selects the SDIO mode and enable the SDIO primary interrupts.

Returns

• none

void sl_si91x_sdio_secondary_send (uint8_t num_of_blocks, uint8_t * data_buf)

Trigger sequence to send data from the SDIO secondary in non-blocking mode to the host/primary device.

This API accepts the num of blocks i.e., one block will have block length (1 to 1024) bytes and a pointer to the data buffer to be transffered.

Returns

• none

sl_si91x_sdio_secondary_receive#

void sl_si91x_sdio_secondary_receive (uint8_t * data_buf)

Receive data on the SDIO secondary in non-blocking mode from the host/primary device using DMA.

Returns

• none

  • SL_STATUS_NULL_POINTER (0x0022) - The parameter is a null pointer

  • SL_STATUS_BUSY (0x0004) - Driver is busy

sl_si91x_sdio_secondary_unregister_event_callback#

void sl_si91x_sdio_secondary_unregister_event_callback (uint32_t flag)

Unregister the SDIO secondary user callback function.

Returns

• none

sl_status_t sl_si91x_sdio_secondary_gpdma_register_event_callback (sl_sdio_secondary_gpdma_callback_t callback_event)

Register the SDIO secondary DMA user callback function.

• Pre-conditions:

  • sl_si91x_sdio_secondary_init();

Returns

• status 0 if successful, else error code as follow SL_STATUS_OK (0x0000) - Success

  • SL_STATUS_NULL_POINTER (0x0022) - The parameter is a null pointer

  • SL_STATUS_BUSY (0x0004) - Driver is busy
