Window Mode
ACIFA Interrupt
ACIFA Output
Each AC has one source of interrupt. The configuration of the source of the interruption is done
by writing in the Interrupt Settings field in the Configuration Register (CONF0.IS and CONF1.IS).
The interrupt can be triggered:
In window mode, the two ACs are grouped. The negative input of ACA and the positive input of
ACB are the same and are defined in the Window Common Input Selection field in the Window
Configuration register (WCONF.WINSEL). The positive input of ACA and the negative input of
ACB are still configured by CONF0.INSELP and CONF1.INSELN.
Like in normal mode, the ACs generate the acout[i] outputs according to the input voltages vip
(AC positive input) and vin
The ACIFA generates a window function signal (acwout) according to the common input voltage
to be compared:
The ACIFA generates two independent events (like in normal mode) according to the configura-
tion of EVSRC0 and EVSRC1:
• as soon as vipB < vinB or
• on toggle of the ACA output (acoutA) or
• on toggle of the ACB output (acoutB)
• as soon as vip > vin
• as soon as vip < vin
• on toggle of the AC output (acout[i])
• acout[i] = 1 if vip
• acout[i] = 0 if vip
• acout[i] = 0 if the AC output is not available (ie. SR.ACRDYi is still 0)
• acwout = 1 if the common input voltage is inside the window, vin
• acwout = 0 if the common input voltage is outside the window, v
• acwout = 0 if the window mode output is not available (ie. The Window Function Ready bit in
• as soon as vipA > vinA or
• as soon as vipA < vinA or
• as soon as vipB > vinB or
• as soon as vipB < vinB or
• as soon as vinB < vcommon < VipA or
• as soon as vcommon < vinB or vcommon > vipA or
• on toggle of the ACA output (acoutA) or
• on toggle of the ACB output (acoutB) or
• on toggle of the window compare output (acwout)
the Status Register (SR.WFRDY) is still 0)
