8-Bit Micro-controller

6.4 Mode 1 (16-bit Counter/Timer)
Mode1 is the same as Mode0, except that the timer register is being run with all 16 bits.

6.5 Mode 2 (8-bit auto-reload Counter/Timer)
Mode 2 configures the timer register as an 8-bit counter(TLx) with automatic reload. Overflow from TLx not only set
TFx, but also reload TLx with the content of THx, which is determined by software. The reload leaves THx
unchanged. Mode 2 operation is the same for Timer0 and Timer1.

6.6 Mode 3 (Timer 0 acts as two independent 8 bit Timers / Counters)
Timer1 in Mode3 simply holds its count, the effect is the same as setting TR1 = 1. Timer0 in Mode 3 enables TL0
and TH0 as two separate 8-bit counters. TL0 uses the Timer0 control bits such like C/T, GATE, TR0, INT0 and TF0.
TH0 is locked into a timer function (can not be external event counter) and take over the use of TR1, TF1 from
Timer1. TH0 now controls the Timer1 interrupt.
