11.8.2 8-Bit Timer/Counter 3, 4 Mode
The 8-bit timer/counter mode is selected by control register as shown in Figure 11.30.
The two 8-bit timers have each counter and data register. The counter register is increased by internal or
external clock input. Timer 3 can use the input clock with one of 2, 4, 8, 32, 128, 512, 2048 and EC3 prescaler
division rates (T3CK[2:0]). Timer 4 can use the input clock with one of 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024,
2048, 4096, 8192, 16384 and timer 3 clock prescaler division rates (T4CK[3:0]). When the value of T3CNT,
T4CNT and T3DR, T4DR are respectively identical in Timer 3, 4, the interrupt Timer 3, 4 occurs.
The external clock (EC3) counts up the timer at the rising edge. If the EC3 is selected as a clock source by
T3CK[2:0], EC3 port should be set to the input port by P00IO bit. Timer 4 can’t use the external EC3 clock.
