Is there a post anywhere that indicates what are the allowed speeds in the
SPI OPEN speed command.
I had a quick look in the manual but did not see anything.

The speeds that will actually be set are CPUspeed/2 divided by 1 to 256

Thanks.

Suggested update to Appendix D

Appendix D - SPI Communications
‘speed’ is the requested speed for the SPI clock. Any value can be requested, the firmware will select the next speed that can be achieved that is equal to or slower than the speed requested. The speed that will actually be set is CPUspeed/2 divided by 1 to 256.
