MOV RCAP2L,#-1000
MOV RCAP2H,#-1000 ;auto reload values

This effectively puts 0x1818 in RCAP2 (-1000 == 0xFC18). Instead of counting 1000 timer ticks it will count 59368 ticks. Have you waited long enough?


YES, I have waited more than enough, I have now tried it with these values

Save This Code
    MOV RCAP2L,#0F0H
    MOV RCAP2H,#0D8H


which ideally should give me overflow after every 1000 usec. But it still is not working.
