13. Program Acceleration via W#/ACC Pin
56
The device is delivered with the memory array erased i.e. all bits are set to 1 (FFh) upon initial factory
shipment. The Status Register and Configuration Register contains 00h (all bits are set to 0).
The Lock Register (address 0x100h) is written to 0x01 and ESN1 (addresses 0x102h-0x109h) are written
with a 64-bit randomly generated, unique number (taken from
