VREFN
66
Input
ADC Reference—This pin is connected to the negative side of the ADC input
range. This pin requires a 0.1
μF ceramic capacitor to VSSA and a start-up time
of 25ms, prior to beginning conversions.
VREFP
65
Input
ADC Reference—This pin is connected to the positive side of the ADC input
range. This pin requires a 0.1
μF ceramic capacitor to VSSA and a start-up time
of 25ms, prior to beginning conversions.
VREFMID
68
Input
ADC Reference—This pin isconnected to the center of the ADC input range.
This pin requires a 0.1
μF ceramic capacitor to VSSA and a start-up time of
25ms, prior to beginning conversions.
VREFLO
64
Input
ADC Reference—These pins are Negative Reference for ADC and are
generally connected to a VSSA.
VREFHI
67
Input
ADC Reference—These pins are Positive Reference for ADC and are
generally connected to a 3.3V Analog (VDDA_ADC) supply.
IRQA
40
Input
(Schmitt)
External Interrupt Request A—The IRQA input is a synchronized external
interrupt request that indicates that an external device is requesting service. It
can be programmed to be level-sensitive or negative-edge-triggered. If
level-sensitive triggering is selected, an external pull-up resistor is required for
wired-OR operation.
If the processor is in the Stop state and IRQA is asserted, the processor will
exit the Stop state.
