1. The average DC current drawn by I/Os between GND connections, or between the last GND in an I/O bank and the end of an I/O bank, as

shown in the logic signal connections 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.
