Let's say that we have CF-card, and we have two devices that
need to have full R/W access to it, one device at the time.
Hence we would need a simple circuit that control access to
CF card either from device A or device B.

Note: dynamic switching is not needed. Switching can be done
at reset, ie. at the press of the button MCU simply memorizes
that another device should have granted access, and enables
access to that device after reset.

Please give me your thoughts how would you approach this
problem.

Any helpful answers much appreciated.

Thank you.
