USB V2.0 High Speed Device Port Introduction
Figure 39-2. Board Schematic
The UDPHS is not continuously clocked.
For using the UDPHS, the programmer must first enable the UDPHS Clock in the Power Man-
agement Controller (PMC_PCER register). Then enable the PLL (PMC_UCKR register).
However, if the application does not require UDPHS operations, the UDPHS clock can be
stopped when not needed and restarted later.
The UDPHS interrupt line is connected on one of the internal sources of the Interrupt Controller.
Using the UDPHS interrupt requires the Interrupt Controller to be programmed first.
Table 39-2.
The USB V2.0 High Speed Device Port provides communication services between host and
attached USB devices. Each device is offered with a collection of communication flows (pipes)
associated with each endpoint. Software on the host communicates with a USB Device through
a set of communication flows.
