have you verified that the SFR addresses are identical? I never used the RD (doing other things those days), only the RD2, but I have had some 'surprises' from the fact that the 66x and the Rx2 have different SFR addresses for the PCA.
Erik Yes I verify all of those register that was my first idea !, that was correct , I use keil software. I find the solution. It was a hardware problem . It fact CEX4 was short to a line on the pcb . This line was the transistor who driving the reset generator. And as soon as the CEX4 goes high , a reset was aserted . Stupid problem !!!! Thanks for your help . |
