When operating in window mode, each channel generates the same ACOUT outputs as in nor-
mal mode, see
Additionally, the ACIFB generates a window mode signal (acwout) according to the common
input voltage to be compared:
When operating in window mode, each channel can generate the same interrupts as in normal
mode, see
Additionally, when channels operate in window mode, programming Window Mode Interrupt Set-
tings in the Window Mode Configuration Register (CONFWn.WIS) can cause interrupts to be
generated when:
• ACWOUT = 1 if the common input voltage is inside the window, V
• ACWOUT = 0 if the common input voltage is outside the window, V
• ACWOUT = 0 if the window mode output is not available (SR.ACRDYn=0 or
• 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).
• When the comparison in both channels in the window pair is ready.
