1. The min VILand max VIH values are based on the respective min and max OVIN values found in Table 3.
2. The symbol VIN, in this case, represents the OVIN symbol found in Table 3.
3. For recommended operating conditions, see Table 3.
4. TDI, TMS, and TRST_B have internal pull-ups per the IEEE Std. 1149.1 specification.
