Ground.
Not connected internally.
Ready. Indicates when valid burst data is ready to be read.
Clock Input. In burst mode, after the initial word is output, subsequent active edges of CLK increment
the internal address counter. Should be at V
Address Valid. Indicates to device that the valid address is present on the address inputs.
When low during asynchronous mode, indicates valid address; when low during burst mode, causes
starting address to be latched at the next active clock edge.
When high, device ignores address inputs.
Hardware Reset. Low = device resets and returns to reading array data.
