Hi,

I am using SBC (tle9273) as the slave which communicates to RH850F1KHD8 microcontroller (Master) through SPI communication.

When I send a command through SPI, MISO and MOSI data are improper even if SCL and CS signal are proper when probed through CRO.

I am using the following configurations as per my slaves requirement

1. SPI FIFO mode selected

2. SPI LSB first

3. SPI Mode1 used for communication

4. Port Muxing are corrected as per my hardware.

5. The Baudrate of SPI is 2MHz

Please guide me on how to configure the SBC in Normal mode. Also please provide me any sample code available for SBC Tle9273 for configuring it.

Thanks in advance.

Hi Sahithi,

can you please provide us a scope-screenshot, showing a 16-bit SPI transmission (SDI, SDO, CLK, CSN)?

Thanks
