for a constant cycle. In this state, the CPU does not start up, even if RESETP is set to
high level. When TRST is set to high level, H-UDI operation is enabled, but the CPU

• Boot request from H-UDI (boot sequence)
• Another RESETP assert (power-on reset)
the emulator (ASE break mode) and a mode to execute the user program (ASE user
