Buffer
Type
Description
RB0
13
13
I/O TTL/ST Bi-directional I/O port/ serial programming data. Can
be software programmed for internal weak pull-up and
wake-up from SLEEP on pin change. This buffer is a
Schmitt Trigger input when used in serial programming
mode.
RB1
12
12
I/O TTL/ST Bi-directional I/O port/ serial programming clock. Can
be software programmed for internal weak pull-up and
wake-up from SLEEP on pin change. This buffer is a
Schmitt Trigger input when used in serial programming
mode.
RB2
11
11
I/O
TTL Bi-directional I/O port.
RB3/MCLR/VPP
4
4
I TTL/ST Input port/master clear (reset) input/programming volt-
age 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.
Can be software programmed for internal weak pull-up
and wake-up from SLEEP on pin change. Weak pull-
up only when configured as RB3. ST when configured
as MCLR.
RB4/OSC2/CLKOUT
3
3
I/O
TTL Bi-directional I/O port/oscillator crystal output. Con-
nections to crystal or resonator in crystal oscillator
mode (XT and LP modes only, RB4 in other modes).
Can be software programmed for internal weak pull-up
and wake-up from SLEEP on pin change. In EXTRC
and INTRC modes, the pin output can be configured to
CLKOUT, which has 1/4 the frequency of OSC1 and
denotes the instruction cycle rate.
RB5/OSC1/CLKIN
2
2
I/O TTL/ST Bidirectional IO port/oscillator crystal input/external
clock source input (RB5 in Internal RC mode only,
OSC1 in all other oscillator modes). TTL input when
RB5, ST input in external RC oscillator mode.
