Description
Write Mode — This control bit defines the write mode of this register.
0 Write to all fields in this register on write access.
1 Write to SEL and IBD field only on write access.
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
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.
Slot ID — Defines the IBD-selected frame ID boundary value for the SEL-selected range filter.
