1. RESET# or HOLD# signals can share pin 1 with DQ3, depending on the selected device
(see Part Numbering Ordering Information). When using single and dual I/O commands
on these parts, DQ3 must be driven HIGH by the host, or an external pull-up resistor
must be placed on the PCB, in order to avoid allowing the HOLD# or RESET# input to
float.
Notes:
2. Pin 3 = RESET# or DNU, depending on the part number. This signal has an internal pull-
up resistor and may be left unconnected if not used.
