Setting the TR0 bit (TCON.4) enables the timer when either GATE0 (TMOD.3) is 0 or the input signal /INT0 is
logic-level one. Setting GATE0 to logic 1 allows the timer to be controlled by the external input signal /INT0,
facilitating pulse width measurements.
Setting TR0 does not reset the timer register. The timer register should be initialized to the desired value before
enabling the timer.
TL1 and TH1 form the 13-bit register for Timer 1 in the same manner as described above for TL0 and TH0. Timer
1 is configured and controlled using the relevant TCON and TMOD bits just as with Timer 0.
17.1.2. Mode 1: 16-bit Counter/Timer
Mode 1 operation is the same as Mode 0, except that the counter/timer registers use all 16 bits. The counter/timers
are enabled and configured in Mode 1 in the same manner as for Mode 0.
