Section 26 USB 2.0 Host/Function Module
The USB 2.0 host/function module is a USB controller which provides capabilities as a USB host
controller and USB function controller function. This module supports high-speed transfer defined
by USB (universal serial bus) Specification 2.0, full-speed transfer, and low-speed transfer when
used as the host controller, and supports high-speed transfer and full-speed transfer when used as
the function controller. This module has a USB transceiver* and supports all of the transfer types
defined by the USB specification.

defined by the USB specification.
This module has an 8-Kbyte buffer memory for data transfer, providing a maximum of ten pipes.
Any endpoint numbers can be assigned to PIPE1 to PIPE9, based on the peripheral devices or user
system for communication.
