MSM80C154S/83C154S/85C154HVS864.5.2.5.4 Mode 2M1 M01 0In mode 2, timer/counters 0 and 1 both become 8-bit timer/counters with 8-bit auto reloaderregisters by the circuit connection shown in Figures 4-15 and 4-16. TH0 and TH1 in timer/counters 0 and 1 serve as the 8-bit auto reloader section, and TL0 and TL1 serve as the timer/counter section.If a carry signal is generated by the 8-bit timer/counter TL0 and TL1, the respective autoreloader register data is preset into the timer/counter, and counting proceeds from the presetvalue.TF0 is set by the timer/counter 0 carry signal, and TF1 is set by the timer/counter 1 carrysignal. Note that the timer/counter 1 carry signal can also be used as the serial porttransmission/reception clock.
