2.3.5 Read Security Memory (SLE 4442 only)
Similar to the read command for the protection memory this command reads out the 4 bytes of the
security memory. The number of clock pulses during the outgoing data mode is 32. I/O is switched
to high impedance Z by an additional pulse. Without a preceeding successful verification of the PSC
the output of the reference bytes is suppressed, that means I/O outputs state L for the reference
data bytes.
