Notes:

1.

For the dedicated parts that don’t have the additional RESET# pin on ball A3, either HOLD# (P7=0) or RESET#

(P7=1) pin can be selected on ball D4 by the P7 bit setting in Read Register when QE=0. For the dedicated parts

with additional RESET# pin on ball A3, only HOLD# pin is selected for ball D4 regardless of the P7 bit of Read

Register when QE=0.

2. The dedicated parts have additional RESET# pin (ball A3) on 24-ball TFBGA 6x8mm package. For the parts,

Function Regist

er Bit0 (RESET# Enable/Disable) will be set to “0”. The RESET# pin is independent of the P7 bit

of Read Register and QE bit of Status Register. The RESET# pin has an internal pull-up resistor and may be left

floating if not used. Call Factory for the RESET# pin option.
