Enabling a portion (0x100 - 0x107) of the user defined semihosting operation number range (0x100 - 0x1FF) to be processed with the help of the existing target event mechanism, to implement a general-purpose Tcl interface for the target available on the host, via semihosting interface. Example usage: - The user configures a Tcl command as a callback for one of the newly defined events (semihosting-user-cmd-0x10X) in the configuration file. - The target can make a semihosting call with <opnum>, passing optional parameters for the call. If there is no callback registered to the user defined operation number, nothing happens. Example usage: Configure RTT automatically with the exact, linked control block location from target.
