Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

Device VBUS Discharge Time (DVBUSDis)
Specifies the VBUS discharge time after VBUS pulsing during
SRP. This value equals:
VBUS discharge time in PHY clocks / 1, 024
The value you use depends whether the PHY is operating at
30 MHz (16-bit data width) or 60 MHz (8-bit data width).
Depending on your VBUS load, this value can need
adjustment.
