TABLE 1-2: PIC18F6X2X/8X2X PINOUT I/O DESCRIPTIONS (CONTINUED) Pin Name Pin Number Pin Type Buffer Type Description PIC18F6X2X PIC18F8X2X Legend: TTL = TTL compatible input CMOS = CMOS compatible input or output ST = Schmitt Trigger input with CMOS levels Analog = Analog input I = Input O = Output P = Power OD = Open Drain (no P diode to VDD) Note 1: Alternate assignment for CCP2/P2A in PIC18F8X2X devices when CCP2MX (CONFIG3H<0>) is not set (all Program Memory modes except Microcontroller). 2: Default assignment for CCP2/P2A when CCP2MX is set (all devices). 3: External memory interface functions are only available on PIC18F8X2X devices. 4: Default assignment for P1B/P1C/P3B/P3C for PIC18F8X2X devices when ECCPMX (CONFIG3H<1>) is set, and for all PIC18F6X2X devices. 5: Alternate assignment for CCP2/P2A in PIC18F8X2X devices when CCP2MX is not set (Microcontroller mode). 6: PORTH and PORTJ (and their multiplexed functions) are only available on PIC18F8X2X devices. 7: Alternate assignment for P1B/P1C/P3B/P3C for PIC18F8X2X devices when ECCPMX (CONFIG3H<1>) is not set. 8: AVDD must be connected to a positive supply and AVSS must be connected to a ground reference for proper operation of the part in User or ICSP modes. See parameter D001A for details. |
