In mode 1, timer/counters 0 and 1 both become 16-bit timer/counters by the circuit connection
shown in Figures 4-13 and 4-14.
TL0 and TL1 in timer/counters 0 and 1 serve as the counter for the eight lower bits, and TH0
and TH1 serve as the counter for the eight upper bits.
TL0 is set by the timer/counter 0 carry signal, and TF1 is set by the timer/counter 1 carry
signal. Again note that the timer/counter 1 carry signal can also be used as the serial port
transmission/reception clock.
