31.6.12
Register Name:
Access Type:
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. TXVDIS is automatically set after a reset, so it must be cleared again
to reenable the transceiver.

The USB transceiver pull-ups are enabled/disabled by writing to the MATRIX_USBPCR register documented in
19.6.7
If the USB pullup is not enabled on DP, the user should not write in any UDP register other than the UDP_ TXVC register. This
is because if DP and DM are floating at 0, or pulled down, then SE0 is received by the device with the consequence of a USB
Reset.
