Configuration Options

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.

No.
