spi_clk_stretch

bool nrf_sqspi_dev_cfg_t::spi_clk_stretch

Enable clock stretching when there is not enough data to transmit Clock stretching is applied when the transmit FIFO gets empty or when DMA can't fetch enough data in time. If this feature is disabled and any of the clock stretching conditions occur, the CSN pin gets unasserted. When the missing data becomes available, the CSN pin gets asserted again and the data is transferred as a new transaction.
