Register summary provides cross references to individual registers.


The ROM table has a configuration parameter TIE_OFF_PRESENT, which, if set to 1, allows for the selective removal of any entry using the entry_present input bus. The entry_present bus contains one bit per ROM table entry. If a given entry_present[n] bit is tied HIGH, then the value in ROMEntry<n>.PRESENT[1:0] is taken directly from the value in the ROM_ENTRY<n> parameter for that entry. If the entry_present[n] input is tied LOW, then a value of 0x3 in ROMEntry<n>.PRESENT[1:0] is modified to read 0x2 to indicate that the value is not present and is not the last entry.
