P1_HTPDNAN3O10V-by-One interface hot plug detect (controller receiver pulls this signal low to indicate its presence to the transmitter). This signal is open-drain at the controller output. A pullup resistor is required at the transmitter.
P1_LOCKNAM4O10V-by-One interface clock detect lock (controller receiver pulls this signal low to indicate clock extraction lock to the transmitter). This signal is open-drain at the controller output. A pullup resistor is required at the transmitter.

See I/O Type Subscript Definition  for more information on I/O definitions.
The system supports 1-lane, 2-lane, 4-lane, or 8-lane operation, based on the bandwidth requirement of the input source. The inputs for any unused data lanes must be left open; not all lanes are used. If the V-by-One video interface is not used at all, the pins should be connected to ground.
The V-by-One port supports limited lane remapping to help optimize board layout. The details are described in V-by-One Interface.
In this document, the terms V-by-One and Vx1 are used interchangeably.
