Configuration Options
Configuration options refer to certain options within the MCU that are programmed into the OTP Program Memory de-
vice 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.
