Description
Port A. These pins are used for GPIO.
Port B. These pins are used for GPIO.
Port C. These pins are used for GPIO.
Port D. This pin is used for general purpose output only.
Timer output 0–1. These signals are the output from the timers.
Timer complement output 0–1. These signals are output from the timers in
PWM DUAL OUTPUT mode.
Timer Input 0–1. These signals are used as the capture, gating and
counter inputs. The T0IN signal is multiplexed T0OUT signals.
Comparator inputs. These signals are the positive and negative inputs to
the comparator.
Comparator output. This is the output of the comparator.
Analog port. These signals are used as inputs to the Analog-to-Digital
Converter (ADC).
ADC reference voltage input.
Note: When configuring ADC using external Vref, PB5 is used as VREF in
28-pin package.
External crystal input. This is the input pin to the crystal oscillator. A crystal
is connected between it and the
this pin is used with external RC networks or external clock drivers to
provide the system clock.
External crystal output. This pin is the output of the crystal oscillator. A
crystal is connected between it and the
Clock input signal. This pin can be used to input a TTL-level signal to be
used as the system clock.
XOUT
pin to form the oscillator. In addition,
XIN
pin to form the oscillator.
