Signal Descriptions

Many signals are available on multiple pins, according to the software configuration of the pin multiplexing

options.

Texas Instruments has developed an application called Pin Mux Utility that helps a system designer select

the appropriate pin-multiplexing configuration for their device-based product design. The Pin Mux Utility

provides a way to select valid IO Sets of specific peripheral interfaces to ensure the pin multiplexing

configuration selected for a design only uses valid IO Sets supported by the device.

1. SIGNAL NAME: The name of the signal passing through the pin.

NOTE

The subsystem multiplexing signals are not described in Table 4-1 and Table 4-33.

2. DESCRIPTION: Description of the signal

3. TYPE: Signal direction and type:

–

I = Input

–

O = Output

–

IO = Input or output

–

D = Open Drain

–

DS = Differential

–

A = Analog

–

PWR = Power

–

GND = Ground

4. BALL: Associated ball(s) bottom

NOTE

For more information, see the Control Module / Control Module Register Manual section of

the Device TRM.

CAUTION

The I/O timings provided in Section 5.10, Timing Requirements and Switching

Characteristics are applicable for all combinations of signals for vin1. However,

the timings are valid only for vin2, vin3, and vin4 if signals within a single

IOSET are used. The IOSETs are defined in the Table 5-35, Table 5-36 and

Table 5-37.

NOTE

For more information, see the Video Input Port section of the Device TRM.
