Taking physical memory location information including Socket value, iMC value, Channel value, Dimm value, Rank value; status register address includes Bus number, Device number, Function number, Offset number as examples, Excel table uses LOOKUP function, IF function to find the status register The function of the address can be:

Bus = LOOKUP (A3, {0,1,2,3}, {3,7, "B", "F"}) &"F"; where A3 refers to the value of the socket;

Device = IF (B3 = 0), then LOOKUP (C3, {0, 1, 2, 3}, {14, 14, 15, 15}); IF (B3 = 1), then LOOKUP (C3, {0, 1, 2, 3}, {17, 17, 18, 18}); where B3 refers to the value of iMC and C3 refers to the value of Channel;

Function = LOOKUP (C3, {0,1,2,3}, {2,3,2,3}); where C3 refers to the value of Channel;

Offset = IF (D3 = 0), then LOOKUP (E3, {0,1,2,3}; {104,106,108, "10A"}); IF (D3 = 1), then LOOKUP (E3, { 0,1,2,3}, {"10C", "10E", "False", "False"}), IF (D3 = 2), then LOOKUP (E3, {0,1,2,3}, {110, 112, "False", "False"}); where D3 refers to the value of Dimm and E3 refers to the value of Rank.
