sahilmgandhi 18:6a4db94011d3 211 *
sahilmgandhi 18:6a4db94011d3 212 * This function prepares the SPI slave device to be ready for a single SPI transaction. It configures
sahilmgandhi 18:6a4db94011d3 213 * the SPI slave device to use the memory supplied with the function call in SPI transactions.
sahilmgandhi 18:6a4db94011d3 214 *
sahilmgandhi 18:6a4db94011d3 215 * When either the memory buffer configuration or the SPI transaction has been
sahilmgandhi 18:6a4db94011d3 216 * completed, the event callback function will be called with the appropriate event
sahilmgandhi 18:6a4db94011d3 217 * @ref nrf_drv_spis_event_type_t. Note that the callback function can be called before returning from
sahilmgandhi 18:6a4db94011d3 218 * this function, because it is called from the SPI slave interrupt context.
sahilmgandhi 18:6a4db94011d3 219 *
sahilmgandhi 18:6a4db94011d3 220 * @note This function can be called from the callback function context.
sahilmgandhi 18:6a4db94011d3 221 *
sahilmgandhi 18:6a4db94011d3 222 * @note Client applications must call this function after every @ref NRF_DRV_SPIS_XFER_DONE event if
sahilmgandhi 18:6a4db94011d3 223 * the SPI slave driver should be prepared for a possible new SPI transaction.
sahilmgandhi 18:6a4db94011d3 224 *
sahilmgandhi 18:6a4db94011d3 225 * @note Peripherals that are using EasyDMA (for example, SPIS) require the transfer buffers
sahilmgandhi 18:6a4db94011d3 226 * to be placed in the Data RAM region. Otherwise, this function will fail
sahilmgandhi 18:6a4db94011d3 227 * with the error code NRF_ERROR_INVALID_ADDR.
sahilmgandhi 18:6a4db94011d3 228 *
sahilmgandhi 18:6a4db94011d3 229 * @param[in] p_instance SPIS instance.
sahilmgandhi 18:6a4db94011d3 230 * @param[in] p_tx_buffer Pointer to the TX buffer.
sahilmgandhi 18:6a4db94011d3 231 * @param[in] p_rx_buffer Pointer to the RX buffer.
sahilmgandhi 18:6a4db94011d3 232 * @param[in] tx_buffer_length Length of the TX buffer in bytes.

sahilmgandhi 18:6a4db94011d3 235 * @retval NRF_SUCCESS If the operation was successful.
sahilmgandhi 18:6a4db94011d3 236 * @retval NRF_ERROR_NULL If the operation failed because a NULL pointer was supplied.
sahilmgandhi 18:6a4db94011d3 237 * @retval NRF_ERROR_INVALID_STATE If the operation failed because the SPI slave device is in an incorrect state.
sahilmgandhi 18:6a4db94011d3 238 * @retval NRF_ERROR_INVALID_ADDR If the provided buffers are not placed in the Data
sahilmgandhi 18:6a4db94011d3 239 * RAM region.
sahilmgandhi 18:6a4db94011d3 240 * @retval NRF_ERROR_INTERNAL If the operation failed because of an internal error.
