ATmega128RFA1
The DDEn bit in the DDRE Register selects the direction of the PORTE pin n. If DDEn
is written logic one, PEn is configured as an output pin. If DDEn is written logic zero,
PEn is configured as an input pin.
• Bit 7:0 – DDE7:0 - Port E Data Direction Register Value
This register allows access to the PORTE pins independent of the setting of the Data
Direction bit DDEn. The port pin can be read through the PINEn Register bit, and
writing a logic one to PINEn toggles the value of PORTEn.
• Bit 7:0 – PINE7:0 - Port E Input Pins Value
If PORTFn is written logic one when the PORTF pin n is configured as an input pin, the
pull-up resistor is activated. To switch the pull-up resistor off, PORTFn has to be written
logic zero or the pin has to be configured as an output pin. If PORTFn is written logic
one when the pin is configured as an output pin, the port pin is driven high (one). If
PORTFn is written logic zero when the pin is configured as an output pin, the port pin is
driven low (zero).
• Bit 7:0 – PORTF7:0 - Port F Data Register Value
The DDFn bit in the DDRF Register selects the direction of the PORTF pin n. If DDFn is
written logic one, PFn is configured as an output pin. If DDFn is written logic zero, PFn
is configured as an input pin.
