Pin Name

Mode 4

Mode 5

Mode 6

Mode 7

PA7

• This pin is left open in the initial state for the Bφ output.

PA6

• This pin is left open in the initial state for the

AS output.

PA5

• This pin is left open in the initial state for the

RD output.

PA4

• This pin is left open in the initial state for the

LHWR

output.

PA3

• This pin is left open in the initial state for the

LLWR

output.

PB0

• This pin is left open in the initial

state for the

CS0 output.

Port D

Port E

PF4 to PF0

• These pins are left open in the

initial state for the address output.

Port H

(Used as a data bus)

Port I

(Used as

a data bus)

• Connect these pins to VCC via a

pull-up resistor or to VSS via a pull-

down resistor, respectively, in the

initial state for the general input.

• Connect these

pins to VCC via a

pull-up resistor or

to VSS via a pull-

down resistor,

respectively

Vref

• Connect this pin to AVcc

Notes: 1. Do not change the initial value (input-buffer disabled) of PnICR, where n corresponds to

an unused pin.

2. When the pin function is changed from its initial state, use a pull-up or pull-down

resistor as needed.
