Abstract
A microcontroller has many internal peripheral devices. The peripheral devices have many registers that can be used to configure the peripheral devices for a particular application. The configuration registers are coupled to a scan path where configuration scan data can be inputted or outputted from an external memory. A utility program is used to precalculate and display appropriate configuration scan data. The utility program can also create an output. The output can be loaded into the external memory or can be a data file. Further, the utility program can extract configuration scan data from the external memory, for debug and test.
