2. For WRITE#, L means any one or more byte write enable signals (BWa#, BWb#, BWc# or BWd#) and BWE# are LOW or
3. BWa# enables WRITEs to DQa’s and DQPa. BWb# enables WRITEs to DQb’s and DQPb. BWc# enables WRITEs to DQc’s
4. All inputs except OE# and ZZ must meet setup and hold times around the rising edge (LOW to HIGH) of CLK.
5. Wait states are inserted by suspending burst.
6. For a WRITE operation following a READ operation, OE# must be HIGH before the input data setup time and held
7. This device contains circuitry that will ensure the outputs will be in High-Z during power-up.
8. ADSP# LOW always initiates an internal READ at the L-H edge of CLK. A WRITE is performed by setting one or more
GW# is LOW. WRITE# = H for all BWx#, BWE#, GW# HIGH.
and DQPc. BWd# enables WRITEs to DQd’s and DQPd. DQPa and DQPb are only available on the x18 and x36 versions.
DQPc and DQPd are only available on the x36 version.
HIGH throughout the input data hold time.
byte write enable signals and BWE# LOW or GW# LOW for the subsequent L-H edge of CLK. Refer to WRITE timing
