threshold_select: Input parameter
Specifies which input voltage channel must be compared against Vcompare.
Allowable values are in the range [0, 7].
acomp_pol: Input parameter
Specifies the polarity for which an interrupt occurs; when voltage level is Above (acomp_pol
= 1) or Below (acomp_pol = 0). Voltage levels are values in the range [0, 7].
Disable the Analog level detect interrupt.
Void ANALOG_Detect_Disable ( void );
None.
Compare the selected input voltage against specified threshold.
