VIF Block Input Signals and Test Conditions
1. Input signals must all be input to the PIF IN (pin 6) in the Test Circuit.
2. All input signal voltage values are the levels at the VIF IN (pin 6) in the Test Circuit.
3. Signal contents and signal levels
4. Bus control condition: VIF SYS = "01", S.TRAP.SW = "1", OVER.MOD.SW = "0"
