You already found out that the interrupt vector for timer 2 is not at the same place as for an intel 8052. Yet you still include < 8052.h >. Who knows what else they moved around. (Well, since I looked, I know. ET2 is at 0xE8 instead of 0xAD.) I think you'd better include < p89v66x.h >. It contains the correct sfr and sbit definitions. Maarten |
