你好!我使用GPIF模式从AD芯片获得数据。我从CyPress网站上读到关于GPIF的注释。有一节关于如何触发单个读波和单个写波。读/写XGPIFSGLDATLX将触发事务。
在GPIF设计器中,我们可以设计4个波形。在这个例子中,有一个读、单写、FiFuad和FIFO写。但是,如果我改变了另一个,就像快速波是单写和第二个是单读。当我从XGPIFSGLATDLX读取数据时,CY68013仍然可以准确地启动单个读事务吗?还是会错误地启动单写波?
我的问题是,CY68013如何确定当我读写XGPIFSGLDATLX以触发事务时,它将使用哪一个波形?
谢谢你的帮助

Hi! I am using the GPIF mode to get data from a AD chip. I read the note about GPIF from the cypress.com. There was a sec
tion about how to trigger a single read wavefrom and a single write wavefrom. read/write XGPIFSGLDATLX will trigger the transaction.
In the GPIF designer, we can design 4 wavefrom. in the example, there are single read, single write, fiforead and fifo write, in other. But if I changed the other, like the fast wavefrom is single write and second is single read. When I read a data from XGPIFSGLDATLX, will the CY68013 still can start the single read transaction exactly? or will it start the single write wavefrom wrongly?
my question is how can the cy68013 determine which wavefrom it is going to use when I read/write the XGPIFSGLDATLX to trigger a transaction?
thank you for your help
