Thank you, I wanted to achieve a small system bus for Oberon devices,
inexpensive, with as few components as possible. I learnt SPI cannot be
addressed, but only chip selected by `CS'. My idea was to drive `CS'
by Oberon through `GPIO' + interrupt, being a master letting only one
party to talk, the other listen, at at time.
Thus having a simple HUB, for some A/D sensors. Alternatively to have
also D/D, D/A outputs.
Designing a small control system, so to speak.
