I/O Pin Leakage Current
Table 1–7 lists the Arria II GX I/O pin leakage current specifications.
Table 1–8 lists the Arria II GZ I/O pin leakage current specifications.
Bus Hold
Bus hold retains the last valid logic state after the source driving it either enters the
high impedance state or is removed. Each I/O pin has an option to enable bus hold in
user mode. Bus hold is always disabled in configuration mode.
Table 1–9 lists bus hold specifications for Arria II GX devices.
