1. Input or I/O leakage current is measured with the pin configured as an input or as an I/O with the output driver tri-stated. It is not measured
with the output driver active. Bus maintenance circuits are disabled.

oC, f = 1.0MHz
3. For top and bottom general purpose I/O pins, when VIH is higher than VCCIO, a transient current typically of 30ns in duration or less with a
peak current of 6mA can occur on the high-to-low transition. For left and right I/O banks, VIH must be less than or equal to VCCIO.
