Timer 1 in Mode 3 simply holds its count. The effect is the same as setting TR1 = 0.
Timer 0 in Mode 3 takes TL0 and TH0 as two separate counters. TL0 uses the Timer 0 control bits:
C/ T , GATE, TR0,
takes over the use of TR1 and TF1 from Timer 1. Thus, TH0 now controls the “Timer 1” interrupt.
Mode 3 is provided for applications requiring an extra 8-bit timer or counter. When Timer 0 is in
Mode 3, Timer 1 can be turned on and off by switching it out of and into its own Mode 3, or can still
be used by the serial port as a baud rate generator, or in fact, in any application not requiring an
interrupt.
