Description
ADC2 Pin Present
When set, indicates that ADC pin 2 is present.
ADC1 Pin Present
When set, indicates that ADC pin 1 is present.
ADC0 Pin Present
When set, indicates that ADC pin 0 is present.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
C2+ Pin Present
When set, indicates that the analog comparator 2 (+) input pin is present.
C2- Pin Present
When set, indicates that the analog comparator 2 (-) input pin is present.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
C1+ Pin Present
When set, indicates that the analog comparator 1 (+) input pin is present.
C1- Pin Present
When set, indicates that the analog comparator 1 (-) input pin is present.
C0o Pin Present
When set, indicates that the analog comparator 0 output pin is present.
C0+ Pin Present
When set, indicates that the analog comparator 0 (+) input pin is present.
C0- Pin Present
When set, indicates that the analog comparator 0 (-) input pin is present.
Software should not rely on the value of a reserved bit. To provide
