The remaining subsections of this chapter describe:
• Section 3.1 "Ball Assignments": Provides a ball assign-
ment diagram and tables listing the signals sorted
according to ball number and alphabetically by signal
name.
• Section 3.2 "Strap Options": Several balls are read at
power-up that set up the state of the SC3200. This
section provides details regarding those balls.
