FWH Multiple Device Selection
The strapping values on ID[3:0] must match the values in the IDSEL field when performing
FWH memory cycles. The device will compare the values on the ID[3:0] pins with the IDSEL
field. If there is a mismatch, the device will ignore the remainder of the cycle. The device will
then enter standby mode when the FWH4/LFRAME pin is high and no internal operation is in
progress. The FWH/LAD[3:0] pins will also be placed in a high-impedance state.
