In the ‘Counter’ function, the register is incremented in response to a 1-to-0 transition at its
corresponding external input pin, T0 or T1. In this function, the external input is sampled
once every machine cycle.
When the samples show a high in one cycle and a low in the next cycle, the count is
incremented. The new count value appears in the register in the machine cycle following
the one in which the transition was detected. Since it takes two machine cycles (12
oscillator periods) for 1-to-0 transition to be recognized, the maximum count rate is 112 of
the oscillator frequency. There are no restrictions on the duty cycle of the external input
signal, but to ensure that a given level is sampled at least once before it changes, it
should be held for at least one full machine cycle. In addition to the ‘Timer’ or ‘Counter’
selection, Timer 0 and Timer 1 have four operating modes from which to select.
The ‘Timer’ or ‘Counter’ function is selected by control bits C/T in the Special Function
Register TMOD. These two Timer/Counters have four operating modes, which are
selected by bit-pairs (M1, M0) in TMOD. Modes 0, 1, and 2 are the same for both
Timers/Counters. Mode 3 is different. The four operating modes are described in the
following text.

T1GATE
Gating control for Timer 1. When set, Timer/Counter is enabled only
while the INT1 pin is high and the TR1 control pin is set. When
cleared, Timer 1 is enabled when the TR1 control bit is set.
6T1C/T
Timer or Counter select for Timer 1. Cleared for Timer operation (input
from CCLK). Set for Counter operation (input from T1 input pin).

T0GATE
Gating control for Timer 0. When set, Timer/Counter is enabled only
while the INT0 pin is high and the TR0 control pin is set. When
cleared, Timer 0 is enabled when the TR0 control bit is set.
2T0C/T
Timer or Counter select for Timer 0. Cleared for Timer operation (input
from CCLK). Set for Counter operation (input from T0 input pin).
