MEMORY BLOCK PROGRAMMING
TheIDT72V73273providesuserswiththecapabilityofinitializingtheentire
Connection Memory block in two frames. To set bits 2,1 and 0 of every
ConnectionMemoryHIGHlocation,settheFullBlockProgramto1,writethe
desiredpatternintotheBlockProgrammingDataBits(BPD2-0),andenable
theBlockProgramEnablebit.Alloftheblockprogrammingcontrolcanbefound
intheControlRegister.

ControlRegisterissettoHIGH,theBlockProgrammingdatawillbeloadedinto
thebits2,1and0ofeveryConnectionMemoryHIGHlocationregardlessofthe
selected data rate for the group. The Connection Memory LOW bits will be
loaded with zeros when the Reset Connection Memory LOW(RCML) bit is

The IDT72V73273 also incorporates a feature termed Group Block
Programming. GroupBlockProgramming,allowssubsectionsoftheConnection

clock cycle. The Group Block Programming function programs "Channel n"
forallstreamsdeliniatedbythegroupbeforegoingto"Channeln+1". AC-code
representation is shown below. The Group Block Programming feature is
composedoftheBlockProgrammingStartAddress(BPSA),theBlockProgram-
mingEndAddress(BPEA),andtheBPEandBPDbitsintheControlRegister.
The BPSA contains a start address for the block programming and BPEA
containsanendaddress.Theblockprogrammingwillstartatthestartaddress
and program until the end address even if the end address is “l(fā)ess” than the
startaddress. Inotherwordsthereisnomechanismtopreventastartaddress
