If set, enables external gate control (pin int0 or int1 for Counter 0 or 1,
respectively). When int0 or int1 is high, and TRX bit is set (see TCON register), a
counter is incremented every falling edge on t0 or t1 input pin
Selects Timer or Counter operation. When set to 1, a Counter operation is
performed. When cleared to 0, the corresponding register will function as a Timer.
Selects the mode for Timer/Counter 0 or Timer/Counter 1, as shown in TMOD
description.
Selects the mode for Timer/Counter 0 or Timer/Counter 1, as shown in TMOD
description.
Function
13-bit Counter/Timer with 5 lower bits in the TL0 or TL1 register and the
remaining 8 bits in the TH0 or TH1 register (for Timer 0 and Timer 1,
respectively). The 3 high order bits of TL0 and TL1 are held at zero.
16-bit Counter/Timer.
8-bit auto-reload Counter/Timer. The reload value is kept in TH0 or TH1,
while TL0 or TL1 is incremented every machine cycle. When TL(x) overflows,
a value from TH(x) is copied to TL(x).
If Timer 1 M1 and M0 bits are set to '1', Timer 1 stops. If Timer 0 M1 and M0
bits are set to '1', Timer 0 acts as two independent 8-bit Timer/Counters.
