17.1.3. Mode 2: 8-bit Counter/Timer with Auto-Reload
Mode 2 configures Timer 0 and Timer 1 to operate as 8-bit counter/timers with automatic reload of the start
value. The TL0 holds the count and TH0 holds the reload value. When the counter in TL0 overflows from
all ones to 0x00, the timer overflow flag TF0 (TCON.5) is set and the counter in TL0 is reloaded from TH0.
If enabled, an interrupt will occur when the TF0 flag is set. The reload value in TH0 is not changed. TL0
must be initialized to the desired value before enabling the timer for the first count to be correct. When in
Mode 2, Timer 1 operates identically to Timer 0. Both counter/timers are enabled and configured in Mode
2 in the same manner as Mode 0.
