The CPU enters this boot when it detects that TRST is HIGH (in other words, when an emulator/debugger is connected). In this mode, the user can program the EMUBOOTCTRL register (at location 0xD00) to instruct the device on how to boot. If the contents of the EMUBOOTCTRL locations are invalid, then the device would default into WAIT Boot mode. The emulation boot allows users to verify the device boot before programming the boot mode into OTP.
