Configuration options refer to certain options within the MCU that are programmed into the device
during the programming 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 using the application
program. All options must be defined for proper system function, the details of which are shown in the
table.
