1. The data is written to the Temperature Control Unit EEPROM when the
Write Request Flag turns ON.
2. The Write Complete Flag turns ON when the data writing operation is com-
pleted. It takes approximately 140 ms to write the data.
3. The Write Complete Flag automatically turns OFF when the Write Request
Flag turns OFF.
Check the Write Complete Flag is ON before turning OFF the Write Request
Flag. If the Write Request Flag is set to OFF before the Write Complete Flag
turns ON the Write Complete Flag will not subsequently turn ON.
