REV. P1.0.6
BIT 7 - 4 - VT Payload Pointer Increment Count[3:0]:
These RESET-upon-READ bit-fields reflect the number of VT Payload Pointer Increment events that the Receive VT-
De-Mapper block has detected since the last read of this register. The Receive VT-Mapper block will increment the
contents within these bit-fields each time that it detects a VT Payload Pointer Increment event within the incoming VT
data-stream.
