Mode 3
Timer1 in Mode3 simply holds its count, and 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.
