Out-of-Range Comparator (ORC)
The Out-of-Range Comparator (ORC) triggers on analog input voltages (VAIN) above the
analog reference1) (VAREF) on selected input pins (GxORCy) and generates a service
request trigger (GxORCOUTy).
Note: These parameters are not subject to production test, but verified by design and/or
characterization.
The parameters in Table 24 apply for the maximum reference voltage
V
AREF = VDDA + 50 mV.
