- MultiSample Data ( M * 4 * 32-bits) (M depends on data reduction)
- Event Builder Tail - (32-bits)
- 27: FIFO backup error (Should only see skip counts if this is 1)
- 26: ApvBufferAddressSyncError - APV frames didn't have the same addresses
- 23:12: SkipCount - Number of MultiSamples that got dumped due to FIFO backup
- 11:00: Number of MultiSamples (M)
- Per Trigger Tail Word 0 (32-bits) - Batcher sub-frame tail 0
- 31:00: Number of valid bytes in data section, excluding tail (2 * 4 + M * 16)
- Per Trigger Tail Word 1 (32-bits) - Batcher sub-frame tail 1
