About Code Examples
2549K–AVR–01/07
Port K is a 8-bit bi-directional I/O port with internal pull-up resistors (selected for each
bit). The Port K output buffers have symmetrical drive characteristics with both high sink
and source capability. As inputs, Port K pins that are externally pulled low will source
current if the pull-up resistors are activated. The Port K pins are tri-stated when a reset
condition becomes active, even if the clock is not running.

Port L is a 8-bit bi-directional I/O port with internal pull-up resistors (selected for each
bit). The Port L output buffers have symmetrical drive characteristics with both high sink
and source capability. As inputs, Port L pins that are externally pulled low will source
current if the pull-up resistors are activated. The Port L pins are tri-stated when a reset

Reset input. A low level on this pin for longer than the minimum pulse length will gener-
ate a reset, even if the clock is not running. The minimum pulse length is given in Table
26 on page 58. Shorter pulses are not guaranteed to generate a reset.
Input to the inverting Oscillator amplifier and input to the internal clock operating circuit.
Output from the inverting Oscillator amplifier.
AVCC is the supply voltage pin for Port F and the A/D Converter. It should be externally
connected to V
nected to V
This is the analog reference pin for the A/D Converter.

available for download on http://www.atmel.com/avr.
This documentation contains simple code examples that briefly show how to use various
parts of the device. Be aware that not all C compiler vendors include bit definitions in the
header files and interrupt handling in C is compiler dependent. Please confirm with the
C compiler documentation for more details.
These code examples assume that the part specific header file is included before com-
pilation. For I/O registers located in extended I/O map, "IN", "OUT", "SBIS", "SBIC",
"CBI", and "SBI" instructions must be replaced with instructions that allow access to
extended I/O. Typically "LDS" and "STS" combined with "SBRS", "SBRC", "SBR", and
"CBR".
