7.6.68 V3LINK_PORT_SEL Register

The V³Link Port Select register configures which port is accessed in I2C commands to unique Rx Port registers 0x4A, 0x4B, 0x4D - 0x7F and 0xD0 - 0xDF. A 2-bit RX_READ_PORT field provides for reading values from a single port. The 4-bit RX_WRITE_PORT field provides individual enables for each port, allowing simultaneous writes broadcast to both of the V³Link Receive port register blocks in unison. The TDES954 maintains separate page control, preventing conflict between sources.

Table 7-86 V3LINK_PORT_SEL (Address 0x4C)

BIT	FIELD	TYPE	DEFAULT	DESCRIPTION
7	RESERVED	R	0x0	Reserved
6	PHYS_PORT_NUM	R	0x0 Port#	Physical port number This field provides the physical port connection when reading from a remote device via the Bi-directional Control Channel. When accessed via local I2C interfaces, the value returned is always 0. When accessed via Bi-directional Control Channel, the value returned is the port number of the Receive port connection.
5	RESERVED	R	0x0	Reserved
4	RX_READ_PORT	R/W	0x0 Port#	Select RX port for register read This field selects one of the two RX port register blocks for readback. This applies to all paged V³Link Receiver port registers. 0: Port 0 registers 1: Port 1 registers When accessed via local I2C interfaces, the default setting is 0. When accessed via Bi-directional Control Channel, the default value is the port number of the Receive port connection.
3:2	RESERVED	R	0x00	Reserved
1	RX_WRITE_PORT_1	R/W	0x0 0x1 for RX Port 1	Write Enable for RX port 1 registers This bit enables writes to RX port 1 registers. Any combination of RX port registers can be written simultaneously. This applies to all paged V³Link Receiver port registers. 0: Writes disabled 1: Writes enabled When accessed via Bi-directional Control Channel, the default value is 1 if accessed over RX port 1.
0	RX_WRITE_PORT_0	R/W	0x0 0x1 for RX Port 0	Write Enable for RX port 0 registers This bit enables writes to RX port 0 registers. Any combination of RX port registers can be written simultaneously. This applies to all paged V³Link Receiver port registers. 0: Writes disabled 1: Writes enabled When accessed via Bi-directional Control Channel, the default value is 1 if accessed over RX port 0.
