We like to implement SPI in slave mode , but our SPI communication is point to point and we not want uses a microcontroller pin to enable/disable pin,. How we can force by software configuration (or Creator) SPI slave always receives data?

   

 

   

thanks

   

microcontroller : CYBL10573-56LQXI

Short from pulling the actual pin low I cannot see that the SCB SPI allows that mode of operation.
