Comparison Based on
event for DQ1 counter
occurred value
* The feedback bit STS_DIR has the default value "0". A hardware interrupt is not triggered when the first change to the
counter value or position value immediately after the technology module is switched on is in the down direction.
Default setting
No hardware interrupts are enabled in the default setting.

Description
Hardware interrupt when a
comparison event for DQ0
occurs as a result of the
selected comparison con-
dition.
No hardware interrupt
when the change of the
counter value for an incre-
mental or pulse encoder
was not caused by a count
pulse
Hardware interrupt when a
comparison event for DQ1
occurs as a result of the
selected comparison con-
dition.
No hardware interrupt
