Abstract:
A method and apparatus determines and sets operating voltage on a JTAG interface by incrementally increasing a test voltage applied thereto. The contents of a register is monitored to detect when the contents switch (change) from a first value to a second value. The voltage occurring at the switch is doubled to establish the operating voltage.
