In the timer mode, the internal machine cycles are counted. So this register is incremented in each machine cycle. So when the clock frequency is 12MHz, then the timer register is incremented in each millisecond. In this mode it ignores the external timer input pin. See more In the counter mode, the external events are counted. In this mode, the timer register is incremented for each 1 to 0 transition of the external input pin. This type of transitions is treated as events. The external input … See more The Mode 0 operation is the 8-bit timer or counter with a 5-bit pre-scaler. So it is a 13-bit timer/counter. It uses 5 bits of TL0 or TL1 and all of the 8-bits of TH0 or TH1. In this example the … See more TMOD(Timer Mode) is an SFR. The address of this register is 89H. This is not bit-addressable.
