The pin description can be found in any device data sheet. The pinout is contained in the data sheet’s Pin Diagrams chapter, which covers various devices depending on the pin or package specifications. The TQFP pinout of the PIC18-Q10 44-pin devices is presented in Figure 1-1.
The Pin Allocation Tables chapter from the PIC18F27/47Q10 data sheetcontains information about the pre-established pin functions. These functionalities that can be configured for each I/O pin are usually input or output of peripheral modules instances. This information varies depending on the device number of pins. If an evaluation board is used, such as the PIC18F47Q10 Curiosity Nano Development Platform, the routing of the pins on the specific board must be known. The information is available at PIC18F47Q10 Curiosity Nano page.
