Used by Texas Instruments tools such as SmartRF Studio and Packet Sniffer to allow in-situ RF testing on customer boards without disturbing the application stored in flash. This mode is similar to flashless test mode except that DFT mechanisms (scan test, RAM BIST, etc) remain unavailable and that FCFG.appTrims (radio trim values) are copied to the beginning of SRAM before the flash is isolated and then the SWD debugging is enabled allowing test programs to be loaded into and run from SRAM. Tools client mode is not password protected but is only allowed if either CCFG is blank or CCFG.permissions.allowToolsClientMode == ALLOWED. Tools client mode can also be used by customers to do end-of-line testing without having to perform multiple flash program cycles.
