HBMMC_NA1_JEDEC_DEVICE_CODE (HBMMC_NA1) Register Bit-Field Summary
| Field Name | Bits | Type | Reset Value | Description |
|---|---|---|---|---|
| OFFSET_128M | 12:4 | rwNormal read/write | 0x0 | 128MB base address offset, supports remapped non-power of 2 memory sizes For interleaved memory, offsets should be multiplied by interleave factor. For example, an offset of 6 must be programmed as 6x4=24 of a 4-way interleave configuration. |
| DENSITY_CODE | 3:0 | rwNormal read/write | 0xA | DENSITY_CODE: 4H: JEDEC Density Code = 4b0011 -> RA[13:0], BA[3:0], CA[5:1] 4H: JEDEC Density Code = 4b0110 -> RA[14:0], BA[3:0], CA[5:1] 8H: JEDEC Density Code = 4b0100 -> RA[13:0], S[0], BA[3:0], CA[5:1] 8H: JEDEC Density Code = 4b1000 -> RA[14:0], S[0], BA[3:0], CA[5:1] //RA[14:13] = 2b11 is invalid 8H: JEDEC Density Code = 4b1010 -> RA[14:0], S[0], BA[3:0], CA[5:1] |
