Address EID0R=0x380 … EID15R=0x39E
Reset
These registers hold the slot IDs of all sync frames received in even communication cycles and used for
clock synchronization. The CC does not change the even ID values from the end of the static part in the
even cycle to the beginning of the NIT in the odd communication cycle.
