The following section focuses on the EP9302 pin signals
from two viewpoints - the pin usage and pad
characteristics, and the pin multiplexing usage. The first
table
signals. The second table
signal multiplexing and configuration options.
Table Q
illustrates the pad type and pad pull type (if any). The
symbols used in the table are defined as follows. (Note: A
blank box means Not Applicable (NA) or, for Pull Type,
No Pull (NP).)
