Please, I need configure the counter1 for counter events, but using keil-debug it does not work. The counter1 configure is:
void RPM_INIT (void) { EA=1; TR1=TF1=0; TMOD=(TMOD&0xF0)|0xd0; TH1=TL1=0; EX1=1; IT1=1; }
The configuration in the debug is OK, TR1=1, but the counter not increment for pulses in P3.3 (INT1). Any ideas where the problem is? Thanks, Fernando
