Note:
1. BVSEL Function:
a. Unconnected or Pulled to OVDD — OVDD = 3.3 V nominal
b. Connected to HRESET — OVDD = 2.5 V nominal
c. Connected to GND — OVDD = 1.8 V nominal
If BVSEL is connected to GND with a series resistor, the resistor value must be 10 Ω or less.
2. These are test signals for factory use only and must be pulled up to OVDD for normal operation.
3. OVDD inputs supply power to the I/O drivers and VDD inputs supply power to the processor core.
4. Internally tied to GND in the 255 CBGA package. This is NOT a supply pin.
