Mode 3
Mode 3 has different operating methods for the two timer/counters. For timer/counter 1, mode 3 simply
freezes the counter. Timer/Counter 0, however, configures TL0 and TH0 as two separate 8 bit count
registers in this mode. The logic for this mode is shown in the figure. TL0 uses the Timer/Counter 0
control bits
C T

, GATE, TR0,
INT0
and TF0. The TL0 can be used to count clock cycles (clock/12
or clock/4) or 1-to-0 transitions on pin T0 as determined by C/T (TMOD.2). TH0 is forced as a clock
cycle counter (clock/12 or clock/4) and takes over the use of TR1 and TF1 from Timer/Counter 1.
Mode 3 is used in cases where an extra 8 bit timer is needed. With Timer 0 in Mode 3, Timer 1 can
still be used in Modes 0, 1 and 2., but its flexibility is somewhat limited. While its basic functionality is
maintained, it no longer has control over its overflow flag TF1 and the enable bit TR1. Timer 1 can still
be used as a timer/counter and retains the use of GATE and INT1 pin. In this condition it can be
turned on and off by switching it out of and into its own Mode 3. It can also be used as a baud rate
generator for the serial port.
