      Tester Connection Condition Specified Condition
      H89-12 (SW1) - H21-13 (VCC) Always Below 1 Ω
      H89-11 (SW2) - H21-14 (VDD) Always Below 1 Ω
      H89-12 (SW1) - Body ground Always 10 kΩ or higher
      H89-11 (SW2) - Body ground Always 10 kΩ or higher
      H89-6 (E) - Body ground Always Below 1 Ω
      for RHD
      Tester Connection Condition Specified Condition
      H89-11 (SW2) - H21-13 (VCC) Always Below 1 Ω
      H89-12 (SW1) - H21-14 (VDD) Always Below 1 Ω
      H89-11 (SW2) - Body ground Always 10 kΩ or higher
      H89-12 (SW1) - Body ground Always 10 kΩ or higher
      H89-6 (E) - Body ground Always Below 1 Ω
