Universal Serial Bus (USB)
12.2
The MCF5272 USB system consists of a protocol state machine which controls the transmitter and
receiver modules. The state machine implements only the USB function state diagram. The MCF5272
USB controller can serve as a USB function endpoint, but cannot serve as a USB host.
12.2.1
A block diagram of the USB module is shown in
functional blocks. These blocks are USB internal transceiver, clock generator, USB control logic, USB
request processor, and endpoint controllers.
