Output compare and time base interrupt
On overflow, the OVF flag of the ARTCSR register is set and an overflow interrupt request is generated if
the overflow interrupt enable bit, OIE, in the ARTCSR register, is set. The OVF flag must be reset by the
user software. This interrupt can be used as a time base in the application.
External clock and event detector mode
Using the f
event detector. In this mode, the ARTARR register is used to select the n
counted before setting the OVF flag.

The external clock function is not available in Halt mode. If Halt mode is used in the
application, prior to executing the HALT instruction, the counter must be disabled by clearing
the TCE bit in the ARTCSR register to avoid spurious counter increments.
