The IOM multiplexer connects the 8 IOM-2 ports to the two integrated ELICs.
The IOM-MUX can be programmed to one of 2 different modes:
MODE 0
• ELIC0 and ELIC1 are connected together: DD00 with DD10, DU00 with DU10, …
MODE 1
• All ELIC0 lines (IOM) reach DOC pins (IOM-2 Ports 0 to 3)
• ELIC1 lines reach ELIC1-Port Multiplexer and are not connected to any ELIC0 line.
