NEe fLPD556 EVACHIP·43 DESCR IPTION The IlPD556 is an evaluation chip for the IlCOM-43/44/45 single chip microcomputers_ Designed to be used for both hardware and software debugging, the EVACH IP-43 is functionally equivalent to the IlCOM-43, except that it does not contain on-chip ROM.
Instead, it is able to address external memory.
In addition, in order to facilitate debugging, the IlPD556 is capable of displaying the contents of the internal accumulator and data pointer and of being single stepped.
When the IlPD556 is being used to evaluate IlCOM-44/45 designs, the external memory capacity should be restricted to that of the respective.
