The logical port description gives logical names to the I/O pins and specifies whether the signals are input,
output, bidirectional, or linkage (power supply). Example 3 shows the DSP56307 logical port description.
Example 4 maps logical signals to the physical pins of the 196-pin PBGA DSP56307 package.
