1. Via MRS or OTF. AL = 0, CWL = 5. R
2. ODTH4 applies to first registering ODT HIGH and then to the registration of the WRITE command. In this example,
1. AL = 0, CWL = 5. R
2. ODTH4 is defined from ODT registered HIGH to ODT registered LOW; in this example, ODTH4 is satisfied. ODT
ODTH4 is satisfied if ODT goes LOW at T8 (four clocks after the WRITE command).
ODTL on
registered LOW at T5 is also legal.
