• ACOUT = 1 if V
INP
> V
INN
• ACOUT = 0 if V
INP
< V
INN
• ACOUT = 0 if the AC output is not available (SR.ACRDY = 0)
The output can optionally be filtered, as described in Section 30.6.6.
30.6.4.2 Normal Mode Interrupt
The AC channels can generate interrupts. The Interrupt Settings field in the Configuration Regis-
ter (CONFn.IS) can be configured to select when the AC will generate an interrupt:
• When V
INP
> V
INN
• When V
INP
< V
INN
• On toggle of the AC output (ACOUT)
• When comparison has been done
30.6.4.3 Normal Mode Peripheral Events
The ACIFB can generate peripheral events according to the configuration of CONFn.EVENN
and CONFn.EVENP.
• When V
INP
> V
INN
or
• When V
INP
< V
INN
or
• On toggle of the AC output (ACOUT)
30.6.5 Window Mode
In window mode, two ACs (an even and the following odd build up a pair) are grouped.
The negative input of ACn (even) and the positive input of ACn+1 (odd) has to be connected
together externally to the device and are controlled by the Input Select fields in the AC Configu-
ration Registers (CONFn.INSELN and CONFn+1.INSELP). The positive input of ACn (even) and
the negative input of ACn+1 (odd) can still be configured independently by CONFn.INSELP and
CONFn+1.INSELN, respectively.
