! ! BANK: FRRD ! ! Source: Master (concatenated from FEP banks) ! Status: Fixed ! When: Event ! Length: Variable ! Type: Unsigned short ! Number: Event Number ! ! Contents: A number of data blocks. ! ! Each data block consists of a header+ data. Header contains a total ! word count, a flag word indicating type of data, the channel number, ! and the start time of the data in clock counts. The MSB of the flag ! word is set for special blocks - currently: ! ! $8000 => End Block, $8001 => Pad block, $8002 =>Swap block. ! ! Special blocks have a truncated (2 word) header. Special blocks should ! be ingnored in analysis. If the upper byte of a data block (ie with ! positive IFLAG) is not zero then this indicates padding in the data. ! Bit 2 of this byte is set if the padding is at the start of the data. ! Bit field 0:1 indicates the number of padding bytes. The data follows ! the header as a number of timeslices, each timeslice being word size ! and containing bytes from two FADC channels, typically ends of the ! same physical wire. ! ! Feb 92: TYPE byte now used as Qt return code when online Qt running, ! set to 0 in all other cases. Three bits in upper byte of flags word ! previously used for Qt return code now reserved. ! !
