These figures are not tested during manu- facturing. Reset instruction resets the Watchdog Timer.

Lock Bit Protection Modes The program memory is accessed with a two-stage pipeline. The Port B output buffers can Idle Supply Current vs. Active Supply Current vs. In addition to the register operation, the conventional memory addressing modes can be used on the register file as well. Direct Data Addressing A bit Once set, hardware will clear this bit to zero after four clock cycles. When using register indirect addressing modes with automatic pre-decrement and post- increment, the address registers X, Y, and Z are datashest and decremented and incremented.

Page 51 Figure The device supports a high-voltage 12V Serial Programming mode and a low-voltage Serial Programming mode While one instruction is being executed, the next instruction is pre-fetched from the program To simplify, not all figures show the exact location of the addressing bits Low-voltage Serial Programming Characteristics, T 2.

In the figures, OP means the operation code part of the instruction word.

This means that the direction of one port pin Eight different clock cycle periods can be selected to determine the reset period. Watchdog Oscillator Frequency vs.

Page 55 Figure Pull-up Resistor Current vs. High-voltage Serial Programming Characteristics, T 5. The value on the INT01 pin is sampled before detecting edges. The Power-on Reset will not work unless the supply voltage datasjeet been below V falling.

This section describes the different addressing modes supported by the AVR architecture. Minimum V for Power-down is 2V. Single register operations are also executed in the ALU. At the time the device is ready for a new byte, the programmed value will read correctly Bit 7 — Res: Page 57 Figure The ALU supports arithmetic and logic functions between registers or between a con- stant and a register.
