10 /* 06Dec99 zm Created so offline can use and after modification for mod 8 DMA reads */
11 /* 08Dec99 zm Changed Event Descriptor Structure to previous length */
12 /* 03Feb00 zm Changed "ushort ZDCDSM[8]" to "BYTE ZDC[16]" in L0_DSM_Data structure */
13 /* 22Jul00 egj Added L0RegBytes and L0RegHeader to trgDataHeaders and TrgSumData. */
14 /* Also added Mult_Reg, ZDC_Reg and Spare_Reg to TrgSumData, making a */
15 /* total of 16 extra bytes. I compensated for this by removing 16 bytes, */
16 /* (4 uints) from L2Result, wich is currently unused. */
17 /* 08Dec00 JMN Changed char hdr[2] in TrgSummary to unsigned short, which is packed */
18 /* 25Feb01 JMN Redesigned and expanded abbreviations to full. */
19 /* 12Mar01 JMN Added additional changes from ZM */
20 /* 30May01 JMN NBNBNBNB Changed FORMAT version from 0x12 to 0x13 */
21 /* 02Jun01 zm defined bit 6 in addBits info FIFO3 for L2.5 abort */
22 /* 27Jun01 JMN Added definition of number of bytes used in trigger summary headers */
23 /* 28Jun01 JMN Added definition of ADD_BITs */
