In the Timer function, the register is incremented every machine cycle. Thus, one can think of it as counting machine cycles. Web8051 timers always count up. When their count rolls over from the maximum count to 0000, they set the corresponding timer flag TF1 or TF0 in TCON. Coun-ters run only while their run flag (TR1 or TR0) is set by the user program. When the run flag is cleared, the count stops incrementing. The 8051 can be setup so chrysler tws maintenance
