Understood. As this special CS manipulation is unique to wspi (wilink spi)  I think the

That sounds like it is going to break normal chip select operation which
doesn't seem like a good idea either.  What exactly are you trying to do
here?  If you need to send some extra bytes at the end of a transfer why
not just do that, or add an empty transfer with a delay.  It's hard to
see what more you could do with only control of the chip select...
