I'm using the S32K144EVB and I want to send more than 1/2/4 bytes using lpspi.
On the "flexio_spi_config" block under the "Advanced" tab, we have the "Transfer size" drop down. But I only have the option to send 1/2/4 bytes, in this case I want to send 6 bytes (48 bits) continuously, having asserted the SS signal continuously while transmitting the 6 bytes.
If I set the transfer size to 2B and set the "Data Tx" of "FlexIO_SPI_Master_Transfer" to a 6 byte vector, it sends the 6 bytes but the SS line is changed at the end of each 2B transferred.
Same is true if I set it to 1B, with the SS line changing after each 1B transferred.
Is there a way to transmit the 6B with the SS line asserted continuously?
