Option
Output
12-bit ADC analog inputs
PCM ADC analog ground reference voltage (should left open or connected
by a bypass capacitor (Ex:100pF) to ground)
PCM ADC analog ground voltage (should connected by a bypass capacitor
(Ex:10 F) to ground)
OP AMP non-inverting input
OP AMP inverting input
OP AMP gain setting output
PWM outputs
Bidirectional 8-bit input/output port. Each bit can be configured as a wake-up
input by a configuration option. Software instructions determine if the pin is a
CMOS output or Schmitt trigger input. Configuration options determine which
pins on this port have pull-high resistors. The output structure can be either
NMOS or CMOS types determined via configuration option.
Bidirectional 8-bit input/output port. Software instructions determine if the pin is
a CMOS output or Schmitt trigger input. Configuration options determine which
pins on this port have pull-high resistors.
Bidirectional 8-bit input/output port. Software instructions determine if the pin is
a CMOS output or Schmitt trigger input. Configuration options determine which
pins on this port have pull-high resistors. Pin PC0 is shared with the buzzer pin
BZ. Pins PC1/PC2 are shared with timer input pins TMR0/TMR1. Pins PC4/
PC5 are shared with Serial Interface pins SDO/SDI. Pin PC6 is shared with the
Serial Interface Slave Select pin. Pin PC7 is shared with the Serial Interface
clock signal.
Bidirectional 8-bit input/output port. Software instructions determine if the pin is
a CMOS output or Schmitt trigger input. Configuration options determine which
pins on this port have pull-high resistors.
Bidirectional 8-bit input/output port. Software instructions determine if the pin is
a CMOS output or Schmitt trigger input. Configuration options determine which
pins on this port have pull-high resistors. PE7 is shared with external interrupt
input INT.
Bidirectional 4-bit input/output port. Software instructions determine if the pin is
a CMOS output or Schmitt trigger input. Configuration options determine which
pins on this port have pull-high resistors.
