No connection − do not connect
† _{I = Input, O = Output, S = Supply, Z = High impedance}
‡ _{Other Pin Characteristics:}
A − Internal pullup (always enabled)
E − Pin is high impedance in HOLD mode (due to HOLD pin).
B − Internal pulldown (always enabled)
F − Pin is high impedance in OFF mode (due to EMU1/OFF pin).
C − Hysteresis input
G − Pin can be configured as a general-purpose input.
D − Pin has bus holder
H − PIn can be configured as a general-purpose output.
J − Internal pullup enabled by the HPE bit in the system register (SYSR)
K − Internal pulldown enabled by the HPE bit in the system register (SYSR)
