RM46L852: How to maintain SPI4 CS low between write and read operation.

Tool/software:

Hi,

I'm trying to read data from a SPI flash using the SPI4 peripheral.

When controling the CS manually (with a gpio) everything is working well. But when I let the SPI4 peripheral control the gpio, I can't get a valid reading.

A simple example would be the JEDEC ID command:

spiBASE_t *base = spiREG4;
spiDAT1_t  data_format = {.CS_HOLD = true,
                          .WDEL = true,
                          .DFSEL = SPI_FMT_0,
                          .CSNR = SPI_CS_0};

uint16_t tx[10] = {JDEC_COMMAND};
uint16_t rx[10] = {0};
spiTransmitData(base, &data_format, 1, tx);
spiReceiveData(base, &data_format, 4, rx);

I suspect that the problems is that the CS is reset in between the Transmit and Receive operation.

How can I make sure CS is kept low?

Please note that I can't use spiTransmitAndReceiveData because I don't want to receive at the same time that I transmit.

Regards,

Gabriel
