All rights reserved. The AVR core combines a rich instruction set with 32 general purpose working regis- ters. All the 32 registers are directly connected to the Arithmetic Logic Unit ALU , allowing two independent registers to be accessed in one single instruction executed in one clock cycle. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers. Block Diagram Figure 1. The interrupt or hardware reset.

Block Diagram Figure 1. The interrupt or hardware reset. GND Ground pin. Port B PB Port pins can provide internal pull-up resistors selected for each bit. A low on this pin for two machine cycles while the oscillator is running resets the device. XTAL1 Input to the inverting oscillator amplifier and input to the internal clock operating circuit.

XTAL2 Output from the inverting oscillator amplifier. When the device is clocked from an external clock source, PB3 is used as the clock input. This concept enables instructions to in one clock cycle. Every program memory constant table look up function.

The stack is registers or between a constant and a register.
