11.2 Introduction
This section describes the universal serial bus (USB) module. The USB
module is designed to serve as a low-speed (LS) USB device per the
Universal Serial Bus Specification Rev. 2.0. Control and interrupt data
transfers are supported. Endpoint 0 functions as a transmit/receive
control endpoint; endpoint 1 functions as interrupt transmit endpoint;
endpoint 2 functions as interrupt transmit or receive endpoint.
