Access:
WARNING: The UDP peripheral clock in the Power Management Controller (PMC) must be enabled before any read/write
operations to the UDP registers including the UDP_TXVC register.
• TXVDIS: Transceiver Disable
When UDP is disabled, power consumption can be reduced significantly by disabling the embedded transceiver. This can
be done by setting TXVDIS field.
To enable the transceiver, TXVDIS must be cleared.
• PUON: Pullup On
0: The 1.5KΩ integrated pullup on DDP is disconnected.
1: The 1.5 KΩ integrated pullup on DDP is connected.
NOTE: If the USB pullup is not connected on DDP, the user should not write in any UDP register other than the UDP_TXVC
register. This is because if DDP and DDM are floating at 0, or pulled down, then SE0 is received by the device with the con-
sequence of a USB Reset.
