Web29 Jun 2024 · Timer mode “3” is a split-timer mode. When Timer 0 is placed in mode 3, it essentially becomes two separate 8-bit timers. That is to say, Timer 0 is TL0, and Timer 1 is TH0. Both timers count from 0 to 255 and overflow back to 0. All the bits that are related to Timer 1 will now be tied to TH0. WebMode 3 configures timer 0 thatso registers TL0 and TH0 operate as separate 8-bit timers. In other words, the 16-bit timer consisting of two registers TH0 and TL0 is split into two independent 8-bit timers. This mode is provided for applications requiring an additional 8-bit timer or counter. Web- 2: 8-Bit auto reload - 3: Split timer mode Mode 0: 13-Bit Timer - Lower byte (TL0/TL1) + 5 bits of upper bytes (TH0/TH1). - Backward compatible to the 8048 - Not generally used Timer operation in Mode 0 Mode 1: 16-bit - All 16 bits of the timer (TH0/TL0, TH1,TL1) are used. - Maximum count is 65,536 chicha meme
