Section 17 USB 2.0 Host/Function Module (USB)
The USB 2.0 host/function module (USB) 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.
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.
