Hello Marc,

Yes, normal SPI (CLK, MOSI, MISO, SEL) plus two GPIOs for flow control.
The CAN peripheral (SPI slave) asserts the additional signals to
request a transfer and to signal that it is busy.

That is rather unlikely. Though, you could buy a building containing
one.

Ok, I'll kick off the process and start to collect the required signatures.
