Fig. 4 Examples of TRG OUT output timing
• EMUOUT pin (green)
This pin outputs a low level when the EMU/ERASE LED is lit (that is, when the
program is being executed) and outputs the 5 V level when that LCD is off (during a
break). This signal can be used as the protect signal for the S5U1C33xxxM emulation
memory.
• TRCFULL pin (blue (right side in the above diagram))
This is the trace full state output pin. This pin outputs a high level when the trace
memory becomes full.
