DPTR Auto Toggle option in UPSD 3354

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.

    yes. it is posible. use assembly for the isr.
    with the c51 stuff c code for interrupts is for whimps. and it is very badly in efficient.
