Figure 5.8 Timer/Counter0, Mode2: 8-Bit Timer/Counter with Auto-Reload
5.1.6 Timer0 – Mode3
In this mode, the TL0 and TH0 are divided into two separate counters. The following Figure
shows the logic for Timer0 running in Mode3. The TL0 uses the Timer0 control bits: C/T, GATE,
TR0, GATE0 and TF0. And the TH0 is locked into a timer function and uses TR1 and TF1 flags
from Timer 1 and controls Timer 1 interrupt. Mode3 is used in applications which require an
extra 8-bit timer/counter. When Timer0 is in Mode3, Timer 1 can be turned on/off by
switching itself into Mode3, or can still be used by the serial channel as a baud rate generator,
or in any application where interrupt from Timer 1 is not required.
