Lucrez cu pic18f252 care comunica prin I2C cu modulul NM7010A (face trecerea spre Ethernet) dar am ceva probleme : incerc sa scriu si sa citesc registrii ai modulului sa vad daca I2C-ul functioneaza OK, dar ceea ce scriu este diferit de ceea ce citesc: dc. de exemplu scriu 0000.0001 citesc 1000.0001 sau dc. scriu 1010.0000 citesc 1110.0000; deci primul bit care il gaseste '0' il scrie sau il citeste '1'.

Nu inteleg care ar putea fi cauza.
