Atmel ATA6612 and ATA6613 support a real Read-While-Write Self-Programming mecha-
nism. There is a separate Boot Loader Section, and the SPM instruction can only execute
from there.
Digital supply voltage.
Ground.
Port B is an 8-bit bi-directional I/O port with internal pull-up resistors (selected for each bit).
The Port B output buffers have symmetrical drive characteristics with both high sink and
source capability. As inputs, Port B pins that are externally pulled low will source current if the
pull-up resistors are activated. The Port B pins are tri-stated when a reset condition becomes
active, even if the clock is not running.
Depending on the clock selection fuse settings, PB6 can be used as input to the inverting
oscillator amplifier.
Depending on the clock selection fuse settings, PB7 can be used as input to the inverting
oscillator amplifier.
If the internal calibrated RC oscillator is used as chip clock source, PB7..6 is used as
TOSC2..1 input for the asynchronous Timer/Counter2 if the AS2 bit in ASSR is set.
The various special features of Port B are elaborated in
