Description
RB0/ICSPDAT
RB0
TTL
CMOS Bidirectional I/O pin. Can be software programmed for internal
weak pull-up and wake-up from Sleep on pin change.
CMOS In-Circuit Serial Programming data pin.
CMOS Bidirectional I/O pin. Can be software programmed for internal
weak pull-up and wake-up from Sleep on pin change.
CMOS In-Circuit Serial Programming clock pin.
CMOS Bidirectional I/O pin.
Input port. Can be software programmed for internal weak
pull-up and wake-up from Sleep on pin change.
Master Clear (Reset). When configured as MCLR, this pin is
an active-low Reset to the device. Voltage on MCLR/V
PP
must
not exceed V
DD
during normal device operation or the device
will enter Programming mode. Weak pull-up always on if
configured as MCLR.
Programming voltage input.
CMOS Bidirectional I/O pin. Can be software programmed for internal
weak pull-up and wake-up from Sleep on pin change.
XTAL
Oscillator crystal output. Connections to crystal or resonator in
Crystal Oscillator mode (XT, HS and LP modes only).
CMOS In EXTRC and INTRC modes, the pin output can be
configured for CLKOUT, which has 1/4 the frequency of OSC1
and denotes the instruction cycle rate.
CMOS Bidirectional I/O pin.
Crystal input.
External clock source input.
CMOS Bidirectional I/O pin.
CMOS Bidirectional I/O pin.
CMOS Bidirectional I/O pin.
CMOS Bidirectional I/O pin.
CMOS Bidirectional I/O pin.
CMOS Bidirectional I/O pin.
Clock input to TMR0.
P
Positive supply for logic and I/O pins.
P
Ground reference for logic and I/O pins.
I = Input, O = Output, I/O = Input/Output, P = Power, — = Not used, TTL = TTL input,
ST = Schmitt Trigger input, HV = High Voltage
