    SLE4428 has a PSC verification logic. All the memory, except
    for the PSC, can always be read. The memory can be written or erased only after PSC verification.
    The error counter can always be written. After eight successive incorrect entries the error counter
    will block any subsequent attempt at PSC verification and hence any possibility to write and erase.
