BIT 0 - RDI-V Insert Type:
This READ/WRITE bit-field permits the user to select the source of the RDI-V code word that the VT-Mapper block will
transmit within the outbound VT-data-stream, as depicted below. In this case, the user has two options.
• To configure the VT-Mapper block to transmit the appropriate RDI-V code (based upon defects that the
corresponding VT-De-Mapper block declares). In this case, the VT-Mapper block will transmit the RDI-V codes, as
configured in the "Channel Control - VT Mapper Block - Ingress Direction - Transmit RDI-V Control Register - Bytes 3
- 1" registers.
• To configure the VT-Mapper block to use the value written into the "Transmit RDI-V Value[2:0]" bit-fields within this
register.
0 - Configures the VT-Mapper block to transmit the appropriate RDI-V code (based upon defects that the
corresponding VT-De-Mapper block declares).
1 - Configures the VT-Mapper block to use the value written into the "Transmit RDI-V Value[2:0]" bit-fields within this
register.
