When the write register protection is enabled (1 is set to bit 0 in the write register protection
register (WR_REG_PROTECT: 0x0021)), this register has to be written in the same Ethernet
frame (value does not care) before other writes to this station are allowed. Write protection is
still active after this frame (if the write register protection register is not changed).
