1. Software default setting.
2. The average DC current drawn by I/Os between adjacent bank GND connections, or between the last GND in an I/O bank and the end of
the I/O bank, as shown in the logic signals connection table, shall not exceed n*8mA. Where n is the number of I/Os between bank GND
connections or between the last GND in a bank and the end of a bank.
3. For 1.8V devices (ispGDX2C) these specifications are VIL = 0.35 VCC and VIH = 0.65VCC
4. For 1.8V power supply devices these specifications are VIL = 0.3 * VCC * 3.3/1.8, VIH = 0.5 * VCC * 3.3/1.8
5. For 1.8V power supply devices these specifications are VIL = 0.35 * VCC * 3.3/1.8 and VIH = 0.5 * VCC * 3.3/1.8
