General Description

Freescale Semiconductor

PTC5/ADC5–PTC0/ADC0

These are shared-function pins. Each pin can be

configured as a standard I/O pin or an ADC input

channel.

See Section 17. Input/Output (I/O) Ports and

Section 12. Analog-to-Digital Converter (ADC).

PTD6/IICSDA

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 open-drain when

configured as output.

See Section 17. Input/Output (I/O) Ports and

Section 14. Multi-Master IIC Interface (MMIIC).

PTD5/IICSCL

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 open-drain when

configured as output.

See Section 17. Input/Output (I/O) Ports and

Section 14. Multi-Master IIC Interface (MMIIC).

PTD4/CLAMP

This is a shared function pin. It can be configured

as a standard I/O pin or the clamp output from the

sync processor.

See Section 17. Input/Output (I/O) Ports and

Section 16. Sync Processor.

PTD3/DDCSCL

This is a shared function pin. It can be configured

as a standard I/O pin or as the clock line of the

DDC12AB module. This pin is open-drain when

configured as output.

See Section 17. Input/Output (I/O) Ports and

Section 15. DDC12AB Interface.

PTD2/DDCSDA

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 open-drain when

configured as output.

See Section 17. Input/Output (I/O) Ports and

Section 15. DDC12AB Interface.

PTD1/D–

PTD0/D+

These are 3.3V, shared function pins. The pins

can be configured as standard I/O pins or USB

interface differential data lines.

See Section 17. Input/Output (I/O) Ports and

Section 13. Universal Serial Bus Module (USB).
