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.

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.
