Address Table
The GT-48001A’s Address Table resides in the local DRAM array. Figure 5 shows the Address Table structure. The
Address Table structure occupies approximately 320Kbytes and is entirely controlled and initialized by the GT-48001A.
Following RESET, the GT-48001A initializes the Address Table by setting all Valid Bits in the table to ‘0’. Every new
address that is learned has its entry’s Valid Bit set to ‘1’. In order to remove an address entry from the table, ONLY the
Skip Bit should be set to ‘1’ (the Valid Bit should not be modified).
Modifications to the Address Table are normally made through GalNet protocol message requests by the CPU. It is
possible to access the Address Table directly, however, this mode is not recommended. Please contact Galileo if you
feel your application requires direct Address Table access.
