请问,EMIF传输时序中是不是一个片选时间内只能传一个数呢,可以在选通周期内传多个数吗?望指教

3.1 Block Move Example
The most basic transfer performed by the DMA is a block move. During device operation it is often
necessary to transfer a block of data from one location to another, usually between on-chip and off-chip
memory.
In this example, data is copied from the external asynchronous memory . A data block of 256 double
words (1024 bytes) residing at CPU word address 78 0000h (external memory CS5 space) needs to be
transferred to internal CPU word address 02 7000h (SARAM, block 31), as shown in Figure 6.
