Appendix BBinary TDC DataThe TDC data has a 32 bit structure. For most values it is sufficient to look atthen in hexadecimal mode, which will be used within this chapter unless otherwisementioned.A new cycle is indicated by two 32 bit sequences. The first indicates the newcycle:followed by0x 110d xxxx }{{}cyclenumber0x xxxx xxxx } {{ }timestampAn event (without zero suppression) consists of 99 32-bit sequences startingwith an event indicator:followed by0x 1109 xxxx }{{}cyclenumber0x xxxx xxxx } {{ }timestampAfter that follows a 32-bit sequence for every channel (hence 96 sequences). Theseare encoded as follows:0x 22 xx }{{}channelx}{{}bbbbxxx }{{}tdcvaluewhere the four unexplained bits can be accounted for hits and width information asfollows:}{{} bb }{{} bbhitwidthThe different values stand for: 00: hit, 01: no hit, 10: OV ROZ and 11: OV ALUfor the hits and 00: no width, 01: small, 10: medium and 11 large for the width103
