plz help me on this topic the problem is that i am interfacing a eeprom with an 8051 ,but the problem is that when the controller is in the middle of a write or read cycle ,there is a possibility that the controller might be interrupted externally which i have also programmed ,the controoller will process the interrupt then come back but till then there might be a kind of loss in protocool what should i do .this is what the datasheet suggests
""MEMORY RESET: After an interruption in protocol, power loss or system reset, any 2-
wire part can be reset by following these steps:
(a) Clock up to 9 cycles, (b) look for SDA high in each cycle while SCL is high and then
(c) create a start condition as SDA is high.""
HAS ANYONE EXPERIENCED THIS PROBLEM PLEASE GUIDE ME ON THIS
