SPI mode 3 on ESP32S3 problem

[Quadglide]

I have some problem setting SPI mode 3 on my ESP32S3. I did find some info about solutions and how to fix it. I tried it but it did not solve the problem. CPOL=1 and CPHA =1 for mode 0. But it is stuck on CPHA = 0. Seems to have been an issue for many years. It works in the Arduino framework but not ESP-IF. (I tried 5.1, 5.2 and 5.3 and same issue)

My code below:

1. // Pin configuration for ST7789
