3.2.4 Interfaces
3.2.4.1 Overview
The TQMa335xL provides interfaces with primary function. These can be used simultaneously independent from its
configuration. If a secondary function (e.g. MII0) is required, some primary functions may be omitted. More information
regarding availability and pinout can be found in the AM335x Data Sheet (1) and the AM335x Reference Manual (3).
