@ Address valid prior to or cOincident with CS tranSition low.
@ If the CS low transition occurs simultaneously with the WE low transition, the
output buffers remain in a high Impedance state.
® WE must be high during all address transitions.
® IWp is measured from the latter of CS or WE going tow to the earher of Cs or WE
going high.
