We are in the process of purchasing PK51 from Keil Indian agent. Right now we are using eval version. We have certain queries, which are given below. 1. In eval version,program starts from 4000H location. From which location, it will start in PK51? 2. Can I set any specific starting location for program in PK51 while using only C proramming and no assembly programming at all? 3. Will PK51 show me all 6 ports of C508 (Infineon make)while in debug mode? Right now eval version only shows 4 ports. 4. can I simulate ADC of C508 in PK51? 5. In eval version, even bit addressable SFRs are shown as full byte register in HEX format. Can I see and manipulate individual bits of bit addressable SFR or SFR in binary format in PK51 (justlike in TASKING, IAR)? Regards Rakesh Parekh
