with a 100nF capacitor as close to the pin as
possible.
A4
GPIO[2]
General-Purpose Input/Output 2. GPIO[2] is in tri-state during boot up. Connect a 100k
pullup or
pulldown resistor to GPIO[2] if not used. The MAX2986 software uses GPIO[2] to control external
USB circuit.
A5
GPIO[22]
General-Purpose Input/Output 22. GPIO[22] is in tri-state during boot up. Connect a 100k
pullup or
pulldown resistor to GPIO[22] if not used. The MAX2986 MAC uses GPIO[22] for AFE interface link
status LED (output) and boot pin bit 1 (input).

General-Purpose Input/Output 17. GPIO[17] is in tri-state during boot up. Connect a 100k
pullup or
pulldown resistor to GPIO[17] if not used.
A8
GPIO[14]
General-Purpose Input/Output 14. GPIO[14] is in tri-state during boot up. Connect a 100k
pullup or
pulldown resistor to GPIO[14] if not used.
A9
GPIO[11]
General-Purpose Input/Output 11. GPIO[11] is in tri-state during boot up. Connect a 100k
pullup or
pulldown resistor to GPIO[11] if not used. The MAX2986 MAC uses GPIO[11] as processor ID, bit 0
(input).
A10
GPIO[9]
General-Purpose Input/Output 9. GPIO[9] is in tri-state during boot up. Connect a 100k
pullup or
pulldown resistor to GPIO[9] if not used. The MAX2986 MAC uses GPIO[9] as serial data in
nonvolatile memory interface.
A11
GPIO[7]
General-Purpose Input/Output 7. GPIO[7] is in tri-state during boot up. Connect a 100k
pullup or
pulldown resistor to GPIO[7] if not used. The MAX2986 MAC uses GPIO[7] as AFE interface power-
down signal.
A12
GPIO[5]
General-Purpose Input/Output 5. GPIO[5] is in tri-state during boot up. Connect a 100k
pullup or
pulldown resistor to GPIO[5] if not used. The MAX2986 MAC uses GPIO[5] as AFE interface serial
data signal.
A13
GPIO[4]
General-Purpose Input/Output 4. GPIO[4] is in tri-state during boot up. Connect a 100k
pullup or
pulldown resistor to GPIO[4] if not used. The MAX2986 MAC uses GPIO[4] for AFE interface serial
clock signal (output) and upper layer interface bit 0 (input).
