Chapter 26: LPC43xx/LPC43Sxx USB1 Host/Device controller
Remark:
For requirements when connecting the USB1_VBUS signal to a USB powered
device-only product or an OTG product, see
26.6 Register description
Remark:
For Full-speed operation with on-chip Full-speed PHY, the pads of the PHY
need to be configured. For configuration of these pads see
.
Remark:
For operations with an external PHY connected through the ULPI interface the
interface needs to be selected in the PTS bits of the PORTSC1 register (
).
ULPI_STP
O
ULPI link STP signal. Asserted to end or interrupt transfers to the PHY.
ULPI_NXT
I
