93 / 165 page  Mode 3 Timer 1 in Mode 3 simply holds its count, the effect is the same as setting TR1 = 0. Timer 0 in Mode 3 established TL0 and TH0 as two separate 8-bit counters. TL0 use the Timer 0 control bits: C/T ,GATE,TR0, INT0 and TF0. TH0 is locked into a timer function (counting machine cycles) and takes over the use of TR1 from Tmer 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.
