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 SC1200/SC1201
processor. This section provides details regarding those
balls.
• Section 3.3 "Multiplexing Configuration": Lists multi-
plexing options and their configurations.
• Section 3.4 "Signal Descriptions": Detailed descriptions
of each signal according to functional group.
