Remarks 1. T = tCYK
2. w: Number of waits inserted due to WAIT
3. wD: Number of waits inserted by DWC0 and DWC1 registers
4. wPR: Number of waits inserted by PRC register
5. i: Number of idle states inserted when a write cycle is inserted after a read cycle
6. wAS: Number of address setup waits inserted by ASC register
7. Observe at least one of the data input hold times tHRDID and tHKID.
8. For the number of w and wD to be inserted, refer to 4.7.3 Relationship between programmable wait
and external wait.
