Periodic Counter Operation Example: Periodic counter operation is obtained for a given
channel’s TCNT by selecting compare-match as a TCNT clear source. Set the TGR register for
period setting to output compare register and select counter clear upon compare-match using the
CCLR2–CCLR0 bits of the timer control register (TCR). After these settings, the TCNT begins
incrementing as a periodic counter when the corresponding bit of TSTR is set to 1. When the
count matches the TGR register value, the TGF bit in the TSR is set to 1 and the counter is cleared
to H'0000. If the TGIE bit of the corresponding TIER is set to 1 at this point, the MTU will make
an interrupt request to the interrupt controller. After the compare-match, TCNT continues counting
from H'0000. Figure 8.8 shows an example of periodic counting.
