byte operation (continued)
In byte-write operation, CASL enables data to be written to the lower byte (DQ0
–
DQ7) and CASU enables data
to be written to the upper byte (DQ8
–
DQ15). In an early-write cycle, WE is brought low prior to both CASx
signals. Data setup and hold times for DQ0
–
DQ15 are referenced to the first falling edge of CASx
(see Figure 5).
