Is it possible to use uPSD3354 option "DPTR Auto Toggle" and "DPTR Auto Increment" in my source code ? Problem: the standard interrupt header do not contain code for saving and initializing this options in DPTC a DPTM registers. Original "memcpy" uses only "manual" DPTR toggle and don't use auto increment of DPTR. Thank you.
Thank you for advices. Today I found "C" intrinsic functions :
_push_(DPTC); _push_(DPTM); DPTM=0; DPTC=0;
and
_pop_(DPTM); _pop_(DPTC);
This functions in ISR serve my problem ...
