We developing embedded device that contains 2 MCU(A and B), both of them can act as master or slave.
The device can run in 3 cases:
1- A + B + eeprom, A master B slave eeprom slave, no problem with that.
2- A + eeprom, A as master eeprom slave, B removed from the circuit, no problem with that.
3- B + eeprom, B as master eeprom slave, here is the problem, B act as slave becouse A control B(in case 1), but now we need that A act as control to control the eeprom, did it's possible to combine this kind of think?
