• Compare operation
When the TQnCE bit is set to 1, 16-bit timer/event counter Q starts counting, and the output signals of the
TOQ00 to TOQ03 and TOQ10
set value of the TQnCCRa register, a compare match interrupt request signal (INTTQnCCa) is generated, and
the output signals of the TOQ00 to TOQ03 and TOQ10
The 16-bit counter continues counting in synchronization with the count clock. When it counts up to FFFFH, it
generates an overflow interrupt request signal (INTTQnOV) at the next clock, is cleared to 0000H, and continues
counting. At this time, the overflow flag (TQnOPT0.TQnOVF bit) is also set to 1. Confirm that the overflow flag is
set to 1 and then clear it to 0 by executing the CLR instruction via software.
The TQnCCRa register can be rewritten while the counter is operating. If it is rewritten, the new value is reflected
at that time by anytime write, and compared with the count value.
Note V850E/IA4 only
Note The TOQ10 pin is provided only in the V850E/IA4.
