RA4/T0CKI/CMP2
RA4
ST
OD Bi-directional I/O port
T0CKI
ST
— External clock input for TMR0 or comparator output. Output
is open drain type
CMP2
—

RA5/MCLR/VPP
RA5
ST
— Input port
MCLR
ST
— Master clear
VPP
HV
— Programming voltage input. 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
RA6/OSC2/CLKOUT RA6
ST
CMOS Bi-directional I/O port.
OSC2 XTAL
— Oscillator crystal output. Connects to crystal resonator in
Crystal Oscillator mode.
CLKOUT —
CMOS In ER/INTRC mode, OSC2 pin can output CLKOUT, which
has 1/4 the frequency of OSC1
RA7/OSC1/CLKIN
RA7
ST
CMOS Bi-directional I/O port
OSC1 XTAL
— Oscillator crystal input
CLKIN
ST
— External clock source input. ER biasing pin.
Legend: ST = Schmitt Trigger input
HV = High Voltage
OD = Open Drain
AN = Analog
