8051 Timer 0 Mode 1 Example Program

This example program shows how to configure timer/counter 0 as a 16-bit timer. An interrupt service routine (ISR) is invoked each time the timer overflows (goes from 0xFFFF to 0x0000). In the ISR, the overflow_count variable increments.

To test this program...

1. Start the debugger.
2. Set a breakpoint on the overflow_count++ line in the ISR.
3. Run the program.

Each time the interrupt routine is invoked, the debugger stops running the program. Position the cursor over the overflow_count variable to view its current value.
