ADC Characteristics
I/O-Ports
All AVR ports have true Read-Modify-Write functionality when used as general digital I/O
ports. This means that the direction of one port pin can be changed without unintentionally
changing the direction of any other pin with the SBI and CBI instructions. The same applies for
changing drive value if configured as output or enabling/disabling of pull-up resistors if config-
ured as input.
In the AT43USB355E, Port F[0:4] are used as the SPI signals for the external serial EEPROM.
Once the data from the SEEPROM are loaded to the SRAM, Port F[1:3] become available as
GPIO pins. Only cycling the power to the chip off and on again will temporarily assign these
pins as SEEPROM interface signals.
Port A
Port A is an 8-bit bi-directional I/O port. The Port A output buffers can sink or source 2 mA.
Three I/O memory address locations are allocated for the Port A, one each for the Data Regis-
ter PORTA, $1B($3B), Data Direction Register (DDRA), $1A($3A) and the Port A Input Pins
(PINA) $19($39). The Port A Input Pins address is read only, while the Data Register and the
Data Direction Register are read/write.
All port pins have individually selectable pull-up resistors. When pins PA0 to PA7 are used as
inputs and are externally pulled low, they will source current if the internal pull-up resistors are
activated.
