the Read Enable 2 (REN2) control input can be grounded (see Figure 14). In
thisconfiguration,theWriteEnable2/Load(WEN2/LD)pinissetLOWatReset
so that the pin operates as a control to load and read the programmable flag
offsets.

controlssignalsofmultipledevices. Acompositeflagshouldbecreatedforeach
oftheend-pointstatusflags(EFandFF). Thepartialstatusflags(AEandAF)
can be detected from any one device. Figure 15 demonstrates a 18-bit word
widthbyusingtwoIDT72V201/72V211/72V221/72V231/72V241/72V251s.
Any word width can be attained by adding additional IDT72V201/72V211/
72V221/72V231/72V241/72V251s.
When these devices are in a Width Expansion Configuration, the Read
Enable 2 (REN2) control input can be grounded (see Figure 15). In this
