Section 25 USB Function Controller (USBF)
Section 25 USB Function Controller (USBF)
This LSI incorporates an USB function controller (USBF).
25.1 Features
• UDC (USB device controller) conforming to USB1.1 processes incorporated USB protocol
automatically.
Automatic processing of USB standard commands for endpoint 0 (some commands and
class/vendor commands require decoding and processing by firmware)
• Transfer speed: Full-speed
• Endpoint configuration: An arbitrary endpoint configuration can be set
The arbitrary endpoint can be configured by setting the correspondence between the endpoint
(the endpoint number used by the USB host) and the EP FIFO number that is provided by this
USB function controller (the transfer method and direction are fixed).
