... NOTES: 1. Pins BUSY and BUSY are both outputs when the part is configured as a master. Both are inputs when configured as a slave. BUSY outputs on the IDT7008 are L R push-pull, not open drain outputs. On slaves the BUSY input internally inhibits writes. 2. "L" if the inputs to the opposite port were stable prior to the address and enable inputs of this port. "H" if the inputs to the opposite port became stable after the address is not met, either BUSY and enable inputs of this port ...

... BUSY indication, and to output that indication. Any number of slaves to be addressed in the same address range as the master, use the BUSY signal as a write inhibit signal. Thus on the IDT7008 RAM the BUSY pin is an output if the part is used as a master (M/S pin = V the BUSY pin is an input if the part used as a slave (M/S pin = V in Figure 3 ...

... The eight semaphore flags reside within the IDT7008 in a separate memory space from the Dual-Port RAM. This address space is accessed by placing a LOW input on the SEM pin (which acts as a chip select for the semaphore flags) and using the other control pins (Address, CE, and R/W) as they would be used in accessing a standard Static RAM ...
