However, PCFG bits are ignored on ports without a corresponding input on device. DS70293B-page 224 Preliminary © 2008 Microchip Technology Inc.
PIC24HJ32GP302/304, PIC24HJ64GPX02/X04, AND PIC24HJ128GPX02/X04 20.0 COMPARATOR MODULE The Comparator module provides a set of dual input Note: This data sheet summarizes the features of the PIC24HJ32GP302/304, PIC24HJ64GPX02/X04, and PIC24HJ128GPX02/X04 families of devices. It is not intended to be a comprehensive reference source. To complement the information in this data sheet, refer to the PIC24H Family Reference Manual, “Section 34. Comparator”, which is available from the Microchip website (www.microchip.com). comparators. The inputs to the comparator can be configured to use any one of the four pin inputs (C1IN+, C1IN-, C2IN+ and C2IN-) as well as the Comparator Voltage Reference Input (CVREF). Note: This peripheral contains output functions that may need to be configured by the peripheral pin select feature. For more information, see Section 10.4 “Peripheral Pin Select” FIGURE 20-1: COMPARATOR I/O OPERATING MODES C1NEG C1IN+ C1IN- VIN- C1EN C1INV CMCON C1OUT (1) C1IN+ CVREF C1POS VIN+ C1 C1OUTEN C2NEG C2IN+ C2IN- VIN- C2EN C2INV CMCON C2OUT (1) C2IN+ CVREF C2POS VIN+ C2 C2OUTEN Note 1: This peripheral’s outputs must be assigned to an available RPn pin before use.
