The Ready/Busy pin is an open-drain output that can be used to identify when the memory array can be read. Ready/Busy is high-impedance during Read mode, Auto Select mode and Erase Suspend mode. After a Hardware Reset, Bus Read and Bus Write operations cannot begin until Ready/Busy be- comes high-impedance. See Table 14 and Figure 10, Reset/Temporary Unprotect AC Characteris- tics. During Program or Erase operations Ready/Busy is Low, VOL. Ready/Busy will remain Low during Read/Reset commands or Hardware Resets until the memory is ready to enter Read mode. The use of an open-drain output allows the Ready/ Busy pins from several memories to be connected to a single pull-up resistor. A Low will then indicate that one, or more, of the memories is busy. Byte/Word Organization Select (BYTE). The Byte/ Word Organization Select pin is used to switch be- tween the 8-bit and 16-bit Bus modes of the mem- ory. When Byte/Word Organization Select is Low, VIL, the memory is in 8-bit mode, when it is High, VIH, the memory is in 16-bit mode.
