Register Description and Programming Model
Table 12-18 describes EPDPn fields.
12.3.3 Configuration RAM
The USB module supports up to 1 KByte of USB descriptors. The configuration RAM
begins
EPCTL0[CFG_RAM_VAL] must be cleared to access the configuration RAM, otherwise
an access error results.
12.3.3.1 Configuration RAM Content
The USB host must configure a device before that device’s function can be used. The host
configures the device by first reading the descriptors for the device. The descriptors must
follow the format described in Chapter 9 of the USB specification and any relevant class
specification.
A device may support multiple configurations. Within any one configuration, the device
may support multiple interfaces. An interface consists of a set of endpoints that presents to
the host a single feature or function of the device. An interface within a configuration may
have alternate settings that redefine the characteristics of the associated endpoints. All
devices must provide a device descriptor and at least one configuration, interface and
endpoint descriptor. Each configuration must have at least one interface and one endpoint
descriptor. Only one configuration is effective at any time, but several interfaces and their
related endpoints may be operational at the same time. Only one setting for a particular
interface is effective at any time.

DATA_PRES Endpoint n data present. This field reflects the number of bytes in the endpoint’s FIFO.
The USB descriptors use little endian format for word and
longword fields. The MCF5272 uses big endian format for
words and longwords. The user must make sure that any word
or longword fields are stored in the correct byte order.

Description
Reserved, should be cleared.
This field is updated when the user writes to or reads from the FIFO and when the control
logic accesses the FIFO. For non-isochronous endpoints, the FIFO level is only updated
when a complete packet is received or transmitted without any errors. This occurs
synchronously with an EOP interrupt. For isochronous endpoints, the FIFO level is
updated by the control logic in real-time rather than only after the transfer of a complete
packet.
Note: for non-isochronous OUT endpoints, this field is frozen while an EOT interrupt is
pending in order to allow the user to determine the number of bytes to read for the last
transfer. For endpoint 0, EPDP0 monitors the OUT FIFO only.
