6.8.3
Each channel is equipped with an 8-bit pre-scale counter, a 24-bit up-timer, a 24-bit compare
register and an interrupt request signal. Refer to Figure 6.8-1 for the timer controller block
diagram. There are three options of clock sources for each channel. Figure 6.8-2 illustrates the
clock source control function. Software can program the 8-bit pre-scale counter to decide the
clock period to 24-bit up timer.
