VT_APS_
INS[1—28][3:0]
Reserved.
APS Software Overwrite Value.
This nibble is pro-
grammed to utilize APS bits in the Z7/K4 byte. This nibble
will be transmitted in bits 1:4 of the Z7/K4 byte.
Reserved.
Enhanced RDI-V Software Overwrite Values.
If
VT_ERDI_EN[1—28] (
Table 211 on page 170
) is a logic 1,
these bits are written into the ERDI-V locations of the Z7
byte.
RDI-V Software Overwrite Values.
If VT_RDI_EN[1—28]
(
Table 211 on page 170
) is a logic 1, this value will be writ-
ten into the RDI-V location of the V5 byte.
RFI-V Software Overwrite Values.
If VT_RFI_EN[1—28]
(
Table 211 on page 170
) is a logic 1, this value will be writ-
ten into the RFI-V location of the V5 byte.

VT_OBIT_
INS[1—28][7:0]
Overhead Values for Software Overwrite in Asynchro-
nous Mappings.
This byte is programmed to utilize the
overhead bits in asynchronous VT/TU mappings.
VT_OBIT_INS[7:4] will be transmitted in the byte following
J2, and VT_OBIT_INS[3:0] will be transmitted in the byte
following Z6/N2.
Z6 Software Overwrite Values.
This byte is programmed
into the outgoing Z6/N2 location when
VT_Z6_INS[1—28][1:0] (
Table 212 on page 171
) = 01.
