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
external clock event detector. In this mode, the ARTARR register is used to select the

n
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.

Input capture function
Input Capture mode allows the measurement of external signal pulse widths through
ARTICRx registers.
