Configuration Options

Configuration options refer to certain options within the MCU that are programmed into the device during the program-

ming process. During the development process, these options are selected using the HT-IDE software development

tools. As these options are programmed into the device using the hardware programming tools, once they are selected

they cannot be changed later as the application software has no control over the configuration options. All options must

be defined for proper system function, the details of which are shown in the table.
