DESCR IPTION
The IlPD556 is an evaluation chip for the Il-43/44/45 single chip microputers_ Designed to be used for both hardware and software debugging, the EVACH IP-43 is functionally equivalent to the Il-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.
