ATTR_MSS_VPD_CKE_MAP TARGET_TYPE_MCS The Memory Clock Enable MAP is a bit map describing the Memory Clock Enable signal to its respective rank. There are 8 bits, but only 4 are currently used [DIMM0 CKE0][DIMM0 CKE1][N/A][N/A][DIMM1 CKE0][DIMM1 CKE1][N/A][N/A] E.g. 0x80 -> 0b10000000, which means DIMM0 CKE0 is mapped to that rank. uint8 0 16 vpd_cke_map 2 2 4
