I'm trying to pause at while (TL0 <= 10) {} until I get a count of 10. When I run the program, the program doesn't pause at while (TL0 <= 10) {}. It's like the while is false. Can any one see something I don't? // Setup TH0 Timer0 for 16-bit counter mode TMOD = (TMOD & 0xF0) | 0x05; //Set the counter0 Run control bit. TR0 = 1; while (1) { //reset Tiimer0 (counter) TL0 = 0; // Toggle P3.4 increment the count while (TL0 <= 10) {} //The rest of the code }
