Note 5-6
Note 5-1: The control signal when writing data is a combination of DACKi_N(i=0, 1), WR0_N and WR1_N.
Note 5-2: The control signal when reading data is a combination of DACKi_N and RD_N.
Note 5-3: The control signal when writing data is a combination of DACK0 and DSTRB0_N.
Note 5-4: The control signal when writing data is a combination of CS_N, WR0_N and WR1_N.
Note 5-5: The control signal when reading data is a combination of CS_N and RD_N.
Note 5-6: When the receipt data is one byte, the data determined time is "(23)td(DREQ-DV)" and the DEND determined
time is "(24)td(DREQ-DendV)".
Note 5-7: RD_N, WR0_N and WR1_N should not be timed to fall at the same time that CS_N is rising. Similarly, CS_N
should not be timed to fall at the same timing that RD_N, WR0_N and WR1_N are rising. In the instances noted
above, an interval must be needed at least 10ns.
Note 5-8:. RD_N, WR0_N and WR1_N should not be timed to fall at the same time that DACKi_N is rising. Similarly,
DACKi_N should not be timed to fall at the same timing that RD_N, WR0_N and WR1_N are rising. In the
instances noted above, an interval must be needed at least 10ns.
