12.2.1.4
The MCF5272 has eight independent endpoint controllers that manage data transfer between the on-chip
CPU and the USB host for each endpoint. These controllers provide event notification to the user and
manage the IN and OUT FIFO dual-port RAM buffers.
The USB endpoint configuration registers (USBEPOCFGn or USBEPICFGn) are used to configure each
endpoint to support either control, interrupt, bulk, or isochronous transfers.
USB always uses endpoint 0 as a control pipe, so it must be configured for control transfer mode.
Additional control pipes can be provided by other endpoints.
A total of 1024 bytes of dual-port RAM are available for transmit and receive FIFO buffers. This RAM is
partitioned to provide 512 bytes for each direction. The user is responsible for configuring the FIFO for
each endpoint. This configuration is flexible within the following constraints:
For example, an endpoint with a maximum packet size of 32 bytes can have a FIFO size of 64, 128, or 256
bytes and a starting address of 0, 64, 128, 192, 256, etc.

request is issued. These standard requests are defined in Chapter 9 of the USB
Request processor clears the feature specified by the feature selector parameter. Currently, remote
wakeup and endpoint halt are the only features defined by the USB specification. If the feature to be
cleared is remote wakeup, the USB block disables the remote wakeup functionality. If the feature to be
cleared is endpoint halt, the request processor activates the selected endpoint. The user is notified
when the remote wakeup is disabled or an endpoint halt is cleared.

Reads the specified device or configuration descriptor from the configuration RAM and transfers it to
the host. Requests for a configuration descriptor returns all of the descriptors associated with a given
configuration including interface, endpoint, and class-specific descriptors. This request fails if the
configuration RAM has not been initialized. No user notification is provided.
The optional requests for string descriptors are not handled automatically by the request processor.

The string descriptors must be stored in external memory and not the configuration RAM.
