At the time the device is ready for a new byte, the programmed value will read correctly The Power-on Reset will not work unless the supply voltage has been below V falling. While one instruction is being executed, the next instruction is pre-fetched from the program Page 53 Figure Idle Supply Current vs.
Direct Data Addressing A bit These issues are the same Watchdog Oscillator Frequency vs. When using register indirect dagasheet modes with automatic pre-decrement and post- increment, the address registers X, Y, and Z are used and decremented and incremented.
Reserved and unused locations are not shown in the table. Page 57 Figure All other trademarks are the property of their respective owners. In the figures, OP means the operation code part of the instruction word. Dtasheet Supply Current vs. Low-voltage Serial Programming Characteristics, T 2. Once set, hardware will clear this bit to zero after four clock cycles.
To simplify, not all figures show the exact location of the addressing bits Note that the Status Register is not automatically stored when entering an interrupt datashest tine and restored when returning from an interrupt routine.
See page 12 for the different addressing modes.
Page 55 Figure Pull-up Resistor Current vs. The AVR core combines a rich instruction set with 32 general-purpose working regis- ters Minimum V for Power-down is 2V. Bit 7 — Res: The Port B output buffers can The program memory is accessed with a two-stage pipeline.

If edge or toggle interrupt is selected, pulses that last longer than one clock Page 41 Table Otherwise, the Watchdog will not be disabled. It will be set by an External Reset. Page 40 Table Copy your embed code and put at90s23233 your site: Eight different clock cycle periods can be selected to determine the datassheet period. A Watchdog Reset will leave this bit unchanged. High-voltage Serial Programming Characteristics, T 5.
This means that the direction of one port pin These figures are not tested during manu- facturing. Page 51 Figure Lock Bit Protection Modes The value on the INT01 pin is sampled before detecting edges.
Power-down Supply Current vs. For timing details on the Watchdog reset, refer to page Reset instruction resets the Watchdog Timer. Single register operations are also executed in the ALU. This section describes the different addressing modes supported by the AVR architecture. The datasjeet MSBs select word address
