3:

â = unimplemented, read as â0â. Shaded cells are not used for A/D conversion.

The RE3 port bit is available only as an input pin when the MCLRE bit in the CONFIG3H register is â0â.

This register is not implemented on PIC18F2331/2431 devices.

These bits are not implemented on PIC18F2331/2431 devices.

4: These pins may be configured as port pins depending on the oscillator mode selected.

5: ANS5 through ANS8 are available only on the PIC18F4331/4431 devices.

6: Not available on 28-pin devices.
