Note:
1. BVSEL Function
If BVSEL is connected to GND with a series resistor, the resistor value must be 10
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.
