According to CIEDGE, this register acts differently. If CIEDGE is level
type, comparator interrupt polarity have level value. If CIEDGE is edge
type, comparator interrupt polarity have edge value.
CIPOLA4
Determine the polarity of Comparator4 Interrupt
0
When High level or rising edge, Interrupt occurs(default)
1
When Low level or falling edge, Interrupt occurs
