12.1.4. Mode 3 Structure
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.
