Adjusted as per the strobe width. 32 MSBs of data mask. For 512-bit, the mask bytes are {DI_MASK_BYTES_2, DI_ MASK_BYTES_1} The data integrity check is not performed on the bytes masked by the DI_MASK_REGISTER. Each bit of DI_MASK_REGISTER represents the byte to be masked. Therefore, a 64-bit register is used for masking the 512-bit wide data bus. |
