Subject: 5416 MP/MC Register Dear All ! I have a question: In the technical reference written that there is MP/!MC Register that selects between MicroProcessor mode to MicroController mode. But the jumper called MP/MC !!!! Is there any difference between MP/!MC and MP/MC ? However setting the jumper on or off doesn't change the value of the cpu register MP/MC !!!! Why is that ? Can someone please help me ?!! REPLY MP/!Mc pin is the correct.If you tie the pin to DVDD it wil operate in Microprocessor mode with external memory, if you tie it to gnd it will operate in Microcontroller mode with onchip ROM . This pin will be sampled only on power on and may be u are changing the jumper while it has already booted and expecting the cpu register to change, which will not happen before power on u should the jumper and the CPU register will be updated correspondigly... regards vinodh |

It is written in technical reference that the default of the IPTR Interrupt vector pointer is FF80h. When I performing reset - I recieve 7F80 instead. Why is that ? Thanks in advance ! REPLY Just check your GEL files while loading the ccs . There you have an option of changing the IPTR and many other cpu register values and before you can see the actual default values in the window this GEL file will change and it may give some other values... regards vinodh |
