1. 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.
2. For 1.5V inputs, there may be an additional DC current drawn from VCC, if the ispMACH 4000ZE VCC and the VCC of the driving device
(VCCd-d; that determines steady state VIH) are in the extreme range of their specifications. Typically, DC current drawn from VCC will be
2µA per input.
