* Unprogrammed IOBs have a default pull-up; this prevents an undefined pad level for unbonded or unused IOBs. Programmed outputs are
default slew-limited.
† Indicates unconnected package pins for the ATT3020.
Note: Table 8 describes the pin assignments for three different chips in two different packages. The function column lists 84 of the 118 pads on
the ATT3042 and 84 of the 98 pads on the ATT3030. Ten pads [indicated with a dagger (†)] do not exist on the ATT3020, which has
74 pads; therefore, the corresponding pins on the 84-pin packages have no connections to an ATT3020.
