If the ESC write protection is enabled (1 is set to bit 0 in the ESC write protection register
(ESC_WR_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. ESC write protection is
still active after this frame (if the ESC write protection register is not changed).
