PEG0 VT Completion Tracking Queue Resource Available
(PEG0VTCTRA)
Number of entries available in PEG0 VT Completion Tracking Queue. 1-based.
The values programmed in the fields below must not be greater than the
value advertised in this field.
Note: If device 6 is also enabled, the default is 01000b; otherwise, it is
10000b.

PEG0 VC0 Write VT Completion Tracking Queue Resource Threshold
(PEG0VC0WRCTQRT)
This field provides a 1-based minimum threshold value used to throttle PEG0
VC0 Write VT fetch. When the number of free PEG0 VT Completion Tracking
Queue entries equals or falls below the value programmed in this field, PEG0
VC0 Write VT fetch is throttled until the number of free PEG0 Completion
Tracking Queue entries rise above this threshold. For example:
00000 = Throttle PEG0 VC0 Write VT Fetch when there is no entry left.
00001 = Throttle PEG0 VC0 Write VT Fetch when there is 1 or less entry left.
00010 = Throttle PEG0 VC0 Write VT Fetch when there is 2 or less entry left.
00011 = Throttle PEG0 VC0 Write VT Fetch when there is 3 or less entry left.
00100 = Throttle PEG0 VC0 Write VT Fetch when there is 4 or less entry left.

PEG0 VC0 Read VT Completion Tracking Queue Resource Threshold
(PEG0VC0RDCTQRTCT)
This field provides a 1-based minimum threshold value used to throttle PEG0
VC0 Read VT fetch. When the number of free PEG0 VT Completion Tracking
Queue entries equals or falls below the value programmed in this field, PEG0
VC0 Read VT fetch is throttled until the number of free PEG0 Completion
Tracking Queue entries rise above this threshold. For example:
00000 = Throttle PEG0 VC0 Read VT Fetch when there is no entry left.
00001 = Throttle PEG0 VC0 Read VT Fetch when there is 1 or less entry left.
00010 = Throttle PEG0 VC0 Read VT Fetch when there is 2 or less entry left.
00011 = Throttle PEG0 VC0 Read VT Fetch when there is 3 or less entry left.
00100 = Throttle PEG0 VC0 Read VT Fetch when there is 4 or less entry left.
