Configuration options refer to certain options within the MCU that are programmed into the OTP
Program Memory 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 by the application software. All options must be defined for proper system
function, the details of which are shown in the table.
