Hello,
in the data sheet of the IWR6843AOP (SWRS237A, p. 46) it is said that the chip select pin of the SPI should be toggled for every 16 bits.
In the reference manual (SWRU522E) of this chip there is nothing to read about it and in a test program I got it working without toggling the pin (SPI clock frequency 10 MHz, 5-Pin operation).
Is there a technical background why toggling should be done or can I rely on the reference manual that toggling is not required?
Best regards,
David
