Figure 6-22. I/O Pin Equivalent Schematic
All registers and bit references in this section are written in general form. A lower case “x” rep-
resents the numbering letter for the port, and a lower case “n” represents the bit number.
However, when using the register or bit defines in a program, the precise form must be used.
For example, PORTB3 for bit no. 3 in Port B, here documented generally as PORTxn. The
physical I/O Registers and bit locations are listed in
page
Three I/O memory address locations are allocated for each port, one each for the Data Regis-
ter – PORTx, Data Direction Register – DDRx, and the Port Input Pins – PINx. The Port Input
Pins I/O location is read only, while the Data Register and the Data Direction Register are
read/write. However, writing a logic one to a bit in the PINx Register, will result in a toggle in
the corresponding bit in the Data Register. In addition, the Pull-up Disable – PUD bit in
MCUCR disables the pull-up function for all pins in all ports when set.
Using the I/O port as General Digital I/O is described in
90. Most port pins are multiplexed with alternate functions for the peripheral features on the
device. How each alternate function interferes with the port pin is described in
Functions” on page
alternate functions.
Note that enabling the alternate function of some of the port pins does not affect the use of the
other pins in the port as general digital I/O.
