Bug with One Shot blocks?

Hi,

 

I have a very strange issue with the ADAU1701 (tested it on the EVAL-ADAU1701MINIZ board).

I use SigmaStudio (x64) V3.9 Build 2 Rev 1246 (I also tested the V3.10 Beta) on a Win7 64Bit Pro.

I've tried to build 2 "Bit pattern generators" (see the attached project).

 

If I set the DC block "Start2" to 1 nothing happens.

If I set the DC block "Start2" back to 0 nothing happens.

If I set the DC block "Start1" to 1 both generators give me the their bit pattern on their GPO pin.

If I set the DC block "Start1"  shortly after this back to 0 the first generator finishes until the one shot block is resetted (as expected).

But the second generator stops immediately - it should not run anyway but it looks like the "Start1" block somehow stops the stop counter of the second generator.

In my opinion this is a bug!

 

Could someone test this please maybe also on the EVAL-ADAU1701MINIZ board?

I've used MP1 and MP10 that are connected to LEDs on the board to see the output visually.

 

Thanks

Christian
