Description
Embedded Characteristics
The USB High Speed Device Port (UDPHS) is compliant with the Universal Serial Bus (USB),
rev 2.0 High Speed device specification.
Each endpoint can be configured in one of several USB transfer types. It can be associated with
one, two or three banks of a Dual-port RAM used to store the current data payload. If two or
three banks are used, one DPR bank is read or written by the processor, while the other is read
or written by the USB device peripheral. This feature is mandatory for isochronous endpoints.
The High Speed USB Host Port A is shared with the High Speed USB Device port and con-
nected to the second UTMI transceiver. The selection between Host Port A and USB Device is
controlled by the UDPHS enable bit (EN_UDPHS) located in the UDPHS_CTRL control register.
