IBD Interval Boundary — This control bit selects the interval boundary to be programmed with the SID value.
0 program lower interval boundary.
1 program upper interval boundary.
SEL Filter Selector — This control field selects the frame ID range filter to be accessed.
00 Select frame ID range filter 0.
01 Select frame ID range filter 1.
10 Select frame ID range filter 2.
11 Select frame ID range filter 3.
