QUESTION

Is there a way to get the 8051 C compiler to use the dual data pointer's of the Dallas high-speed micro while copying memory? I don't want to resort to assembly.

ANSWER

Yes, there is. In C51 V5.xx, the MODDP2 directive uses the extra data pointer when you use the memcpy, memcmp, memmove, strcpy, and strcmp library routines.
