Notes:
1. V_OH does not apply to open-drain output pins.
2. I_OH2 applies to all other outputs.
3. I_OZ applies to all output and bidirectional pins. Tests are performed at V_IN = 0 V and at V_DD only.
4. I_IX applies to all input pins except TDI, TCLK, and TMS pins.
5. I_IL and I_IH apply to the TDI, TCLK, and TMS pins.
6. Parameter not tested. Value determined by characterization.
7. C_CLK applies only to the CLK pin.
8. V_OUT reflects output levels prior to 1: √ 2 transformer state.
