Section 23 USB 2.0 Host/Function Module (USB)
The USB 2.0 host/function module (USB) provides capabilities as a USB host and USB function
and supports high-speed and full-speed transfers defined by USB specification 2.0. 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 eight pipes.
Any endpoint numbers can be assigned to PIPE1 to PIPE7, based on the peripheral devices or user
system for communication.
Note: * The internal USB transceiver must be set before this module is used. For details, see
section 23.5.2, Procedure for Setting the USB Transceiver.
23.1 Features
(1) Host Controller and Function Controller Supporting USB High-Speed Operation
• The USB host controller and USB function controller are incorporated.
• The USB host controller and USB function controller can be switched by register settings.
• Both high-speed transfer (480 Mbps) and full-speed transfer (12 Mbps) are supported.
• High-speed/full-speed USB transceiver (shared by the USB host and USB function) is
incorporated.
(2) Reduced Number of External Pins and Space-Saving Installation
• On-chip D+ pull-up resistor (during USB function operation)
• On-chip D+ and D- pull-down resistor (during USB host operation)
• On-chip D+ and D- terminal resistor (during high-speed operation)
• On-chip D+ and D- output resistor (during full-speed operation)
(3) All Types of USB Transfers Supported
• Control transfer
• Bulk transfer
• Interrupt transfer (high bandwidth transfers not supported)
• Isochronous transfer (high bandwidth transfers not supported)
(4) Internal Bus Interfaces
• Two DMA interface channels are incorporated.
