CY7C68013A GPIF implementation

Anonymous · ‎Oct 12, 2012

Hello evereone!

At the moment i am trying to implement parallel interface on CY7C68013A. And i face with such problem: how i can programming two of GPIF waveforms as one type of transers, single write, for instance. GPIFWFSELECT regester respond for this, by default, one waveform is assigned to each transfer type, but how to use it in my case i don't understand.

Hi,

You can programmatically select the waveforms by assigning the appropriate value for waveform (WF 0/1/2/3) to GPIFWFSELECT register. Say for example, if WF 0 and WF1 are single write waveforsm, then

- to execute WF0, assign the SINGLEWR1:0 fields of GPIFWFSELECT register value of 00, and then trigger SINGLE WR transfers.

- to execute WF1, assign the SINGLEWR1:0 fields of GPIFWFSELECT register value of 01, and then trigger SINGLE WR transfers.
