VPI = 0 enabled. NOTE: All entries in the VPI
Index table must be initialized. If VPI is disabled,
set VP_EN = 0.
Allowable VCI range is 0 to 0x43F.
VCI Index table is located at 0x8050 in
SAR-shared memory.
Initial block of 64 VCC table entries is 0.
Must initialized to 0.
Enable FIFO buffer Full EPD.
Table Entry is enabled. All VCC table entries that
have a path through the VPI/VCI lookup space
must be initialized. If entry is disabled, set
