When configured as MCLR, this pin is an active low Reset to the device. Voltage on MCLR/VPP must not exceed VDD during normal device operation. VPP — — Programming voltage input RA6/OSC2/CLKOUT RA6 ST CMOS Bidirectional I/O port OSC2 — XTAL Oscillator crystal output. Connects to crystal or resonator in Crystal Oscillator mode. CLKOUT — CMOS In RC/INTOSC mode, OSC2 pin can output CLKOUT, which has 1/4 the frequency of OSC1. RA7/OSC1/CLKIN RA7 ST CMOS Bidirectional I/O port OSC1 XTAL — Oscillator crystal input CLKIN ST — External clock source input. RC biasing pin. RB0/INT RB0 TTL CMOS Bidirectional I/O port. Can be software programmed for internal weak pull-up. INT ST — External interrupt RB1/RX/DT RB1 TTL CMOS Bidirectional I/O port. Can be software programmed for internal weak pull-up. RX ST — USART receive pin DT ST CMOS Synchronous data I/O RB2/TX/CK RB2 TTL CMOS Bidirectional I/O port. Can be software programmed for internal weak pull-up. TX — CMOS USART transmit pin CK ST CMOS Synchronous clock I/O RB3/CCP1 RB3 TTL CMOS Bidirectional I/O port. Can be software programmed for internal weak pull-up. CCP1 ST CMOS Capture/Compare/PWM I/O Legend: O = Output CMOS = CMOS Output P = Power — = Not used I = Input ST = Schmitt Trigger Input TTL = TTL Input OD = Open Drain Output AN = Analog |
