How to change the polarity of PCS when configuring DSPI using SDK

Question asked by 张松 张 on Jun 15, 2018

I use the SDK to configure the DSPI module to communicate with EEPROM based on the MPC5744 chip. I need to change the polarity of the PCS, and at some times I need to pull it up or down, but the PCS configured by the SDK is always high or low. The corresponding function for modifying the polarity of PCS can not be found in the dspi_driver.c file. Can we modify the polarity of the PCS directly through the functions of PINSDRVSetPins and PINSDRVClearPins when communicating with SPI? Look forward to your reply!
