Table 62: Register 0x0580:0x05E1 (MFC IO Config)
The content of this address block in the ESC Parameter RAM can be automatically loaded from the SII EEP-
ROM after reset/power-up as a configuration vector that is written to addresses 0x0580:0x05E1 in the ESC’s
memory space.
The respective data in the SII EEPROM must be of Category 1!
Nevertheless, MFC IO configuration data can also be written and updated online by the EtherCAT Master
via the ECAT interface or from a local application controller via the PDI interface by directly accessing
addresses 0x0580:0x05E1 in the ESC’s memory space.
More information on the individual configuration bytes in this configuration vector is given in Section 7.4 –
SII EEPROM MFC IO Block Parameter Map and its following sections.
Example configurations are given in Section 7.10.
