– During the Data portion of a Write sequence, all four bytes (D[35:0]) are
written into the device.
L-H During the Data portion of a Write sequence, all four bytes (D[35:0]) are
written into the device.
– During the Data portion of a Write sequence, only the lower byte (D[8:0]) is
written into the device. D[35:9] will remain unaltered.
