Description
Oscillator crystal input or external clock source input. This
buffer is a Schmitt Trigger input when configured in RC
oscillator mode and a CMOS input otherwise.
Oscillator crystal output. Connects to crystal or resonator
in crystal oscillator mode. In RC mode, OSC2 pin outputs
CLKOUT which has 1/4 the frequency of OSC1, and
denotes the instruction cycle rate.
Master clear (reset) input or programming voltage input.
This pin is an active low reset to the device.
PORTA is a bi-directional I/O port. The AN and V
plexed functions are used by the PIC16C924 only.
PORTB is a bi-directional I/O port. PORTB can be software
programmed for internal weak pull-ups on all inputs.
PORTC is a bi-directional I/O port.

L = LCD Driver
ST = Schmitt Trigger input
RA0 can also be Analog input0.
RA1 can also be Analog input1.
RA2 can also be Analog input2.
RA3 can also be Analog input3 or A/D Voltage Refer-
ence.
RA4 can also be the clock input to the Timer0
timer/counter. Output is open drain type.
RA5 can be the slave select for the synchronous serial
port or Analog input4.
RB0 can also be the external interrupt pin. This buffer
is a Schmitt Trigger input when configured as an exter-
nal interrupt.
Interrupt on change pin.
Interrupt on change pin.
Interrupt on change pin. Serial programming clock.
This buffer is a Schmitt Trigger input when used in
serial programming mode.
Interrupt on change pin. Serial programming data.
This buffer is a Schmitt Trigger input when used in
serial programming mode.
RC0 can also be the Timer1 oscillator output or
Timer1 clock input.
RC1 can also be the Timer1 oscillator input.
RC2 can also be the Capture1 input/Compare1 out-
put/PWM1 output.
RC3 can also be the synchronous serial clock
input/output for both SPI and I
RC4 can also be the SPI Data In (SPI mode) or data
I/O (I
RC5 can also be the SPI Data Out (SPI mode).
