QS53807CQ Datasheet

the interface is flexible, and allows either DMA or non-DMA data transfers, interrupt or non-interrupt driven. It further allows maximum line utilization by providing early interrupt mechanism for buffered (only the information field can be transferred to memory) Tx command overlapping. It also provides separate Rx and Tx interrupt output channels for ef- ficient operation. The 8273 keeps the interrupt re- quest active until all the associated interrupt results have been read.

EMRS cycle is not mandatory and the EMRS command needs to be issued only when PASR is used. The default state without EMRS command issued is all full array refreshed. The device is now ready for the operation selected by EMRS. For operating with PASR, set PASR mode in EMRS setting stage. In order to adjust another mode in the state of PASR mode, additional EMRS set is required but power up sequence is not needed again at this time. In that case, all banks have to be in idle state prior to adjusting EMRS set.
