Simple toggle DPI pins

I'm using some ADSP-21489 DSPs and try to find a simple way to toggle DPI pins without using the SRU macro.

The functionality is set once after booting as GPO pin but the status should be changed during runtime.


I have used all FLAGS (mapped them to AMI data and address pins and FLAG pins) so I can't do it by set/clr flags ....

I still have signals to toggle but the SRU macro needs 15 cycles each time which I want to avoid (need to save cycles).


Is there a way to toggle a DPI (or DAI) pin like e.g. bit set DPI_xxx_whatever BIT_x .... ??


Thanks in advance!
