ACIFA Interrupt
Like in normal mode, each AC has one source of interrupt. The configuration of the source of
interruption is set in CONF0.IS and CONF1.IS. The interrupt can be triggered:
An additional source of interrupt can be generated in window mode. Its configuration is set in the
Window Interrupt Settings field in the Window Configuration register (WCONF.WIS). The source
of interrupt can be triggered:
Each Analog Comparator has one positive and one negative input. Each input may be chosen
among one external input pin in addition to some internal signals. The user writes the input
selection:
Three internal inputs are available for the Analog Comparator.
It is possible to enable High-speed mode by writing a one to the Speed Selection bit in the
CONF register (CONFi.SS) to get the shortest possible propagation delay. This mode consumes
more power than the default low power mode (when CONFi.SS is written to zero) that has a lon-
ger propagation delay.
The user can select between no, low, and high hysteresis, by writing in the Hysteresis Selection
field in the CONF register (CONFi.HS). Adding hysteresis can avoid constant toggling of the
compare output if the input signals are very close to each other.
After enabling an Analog Comparator, the comparison is available after a start-up time defined in
the Start Up Time field in the Start Up Time register (SUT.SUT). During this time the AC output
is not available. The status bit SR.ACRDYi gives the information that the ACi has its output avail-
able or not. In window mode the window mode output is available (SR.WFRDY is one) if both
comparator outputs are available (SR.ACARDY and SR.ACBRDY are both one).
• as soon as vip > vin
• as soon as vip < vin
• on toggle of the AC output (acout[i])
• as soon as the common input voltage is inside the window
• as soon as the common input voltage is outside the window
• on toggle of the window compare output (acwout)
• in normal mode by writing in the Positive Input Selection field (CONFi.INSELP) and in the
• in window mode by writing in the CONF0.INSELP, WCONF.WINSEL and CONF1.INSELN
Negative Input Selection field in the Configuration register (CONFi.INSELN)
fields. In this case the WCONF.WINSEL field overrides the CONF0.INSELN and
CONF1.INSELP fields.
