Description
32KHz Input Clock Available
When set, indicates an even CCP pin is present and can be used as a
32-KHz input clock.
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.
CCP3 Pin Present
When set, indicates that Capture/Compare/PWM pin 3 is present.
CCP2 Pin Present
When set, indicates that Capture/Compare/PWM pin 2 is present.
CCP1 Pin Present
When set, indicates that Capture/Compare/PWM pin 1 is present.
CCP0 Pin Present
When set, indicates that Capture/Compare/PWM 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.
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.
C1o Pin Present
When set, indicates that the analog comparator 1 output pin is present.
