• check the mode setting p0mod0 of the p00/test0 pin in your program.
      when using the on-chip emulator, use the p00/test0 pin as an input pin for on-chip debugging. if p0mod0 is set to input disabled or output enabled, communication with the on-chip emulator will be disabled, and "ice error: 6603h" will occur, making debugging impossible.
      set p0mod0 to the initial value 05h.
