In this mode, the counter is decremented by an external event signal (count source) input to the TRJIO pin.
Various periods for counting events can be set by bits TIOGT0 and TIOGT1 in the TRJIOC register and the
TRJISR register. In addition, the filter function for the TRJIO input can be specified by bits TIPF0 and TIPF1 in
the TRJIOC register.
Also, the output from the TRJO pin can be toggled even in event counter mode.
When event counter mode is used, refer to 15.5 Notes on Timer RJ (3).
Figure 15.5 shows an Operation Timing Example in Event Counter Mode.
