USB
The EVAL-STR910 demonstration board supports USB 2.0 compliant full-speed
communication via a USB type-B connector (CN3). The ESD protection device U6
(USBLC6-2P6) is connected between CN3 and the microcontroller. The USBLC6-2P6 is a
monolithic application-specific device dedicated to ESD protection of high-speed interfaces
such as USB 2.0, Ethernet links and video lines. Two clock sources are available for the
USB:

HDD_DMACK signal is used by the host in response to DMARQ to initiate DMA
transfer. For PIO mode transfer this signal is not used.
– Current version does not support the DMA mode transfer.
– 1:2 to select P76 as HDD_CS1, fit jumper into pin 1 and 2 of J11
– 2:3 to select P55 as HDD_CS1, fit jumper into pin 2 and 3 of J11. Current
version does not support the DMA mode transfer
Enables the external USB 48 MHz clock source.
To use an external oscillator via P27 of the STR91xF for the USB clock
input, JP17 is fitted.
To use the internal clock of the STR91xF, JP17 is not fitted
Default setting: not fitted
Fit the jumper between pin 1 and 2 of JP9. 1.5 kΩ resistors pull-up
controlled by this jumper.
