PIN DESCRIPTION
These are shared-function, bidirectional I/O port
pins. Each pin can be configured as a standard I/O
pin or a PWM output channel.
See Section 19. Input/Output (I/O) Ports and
Section 12. Pulse Width Modulator (PWM).
High voltage reference input to ADC module.
Low voltage reference input to ADC module.
This pin is a standard bidirectional I/O pin.
See Section 19. Input/Output (I/O) Ports.
These are shared-function, bidirectional I/O port
pins. Each pin can be configured as a standard I/O
pin or an ADC input channel.
See Section 19. Input/Output (I/O) Ports and
Section 13. Analog-to-Digital Converter (ADC).
This is a shared-function pin. It can be configured
as a standard I/O pin or the data line of the multi-
master IIC module. This pin is +5V open-drain
when configured as output.
See Section 19. Input/Output (I/O) Ports and
Section 15. Multi-Master IIC Interface (MMIIC).
This is a shared function pin. It can be configured
as a standard I/O pin or the clock line of the multi-
master IIC module. This pin is +5V open-drain
when configured as output.
See Section 19. Input/Output (I/O) Ports and
Section 15. Multi-Master IIC Interface (MMIIC).
This is a shared function pin. It can be configured
as a standard I/O pin or the data line of the
DDC12AB module. This pin is +5V open-drain
when configured as output.
See Section 19. Input/Output (I/O) Ports and
Section 16. DDC12AB Interface.
This is a shared function pin. It can be configured
as a standard I/O pin or the clock line of the
DDC12AB module. This pin is +5V open-drain
when configured as output.
