Eight different at990s2323 cycle periods can be selected to determine the reset period. Elcodis is a trademark of Elcodis Company Ltd. The Lock bits can only be erased with the Chip Erase operation. Page 53 Figure Download datasheet 2Mb Share this page. 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 To simplify, not all figures show the datasgeet location of the addressing bits The value on the INT01 pin is sampled before detecting edges.

Copy your embed code and put on your site: The AVR core combines a rich instruction set with 32 general-purpose working regis- ters It will be set by an External Reset.
Page 40 Table Lock Bit Protection Modes These issues are the same Minimum V for Power-down is 2V. For timing details on the Watchdog reset, refer to page These figures are not tested during manu- facturing. Pull-up Resistor Current vs. Power-down Supply Current vs. Page 57 Figure While one instruction is being executed, the next instruction is pre-fetched from the program Page 51 Figure In addition to the register operation, the conventional memory addressing modes can be used on the register file as well.
Once set, hardware will clear this bit to zero after four clock cycles. Low-voltage Serial Programming Characteristics, T 2. The Company assumes no responsibility for any errors which may appear in this document, reserves the right to change devices or specifications detailed herein at any time without notice, and does not make any commitment to update the information contained herein Page 41 Table Note that the Status Register is not automatically stored when entering an interrupt rou- tine and restored when returning from an interrupt routine.
Active Supply Current vs. Reset instruction resets the Watchdog Timer. The Port B output buffers can The Power-on Reset will not work unless the supply voltage has been below V falling. Reserved and unused locations are not shown in the table. This means that the direction of one port pin Idle Supply Current vs. High-voltage Serial Programming Characteristics, T 5.
The device supports a high-voltage 12V Serial Programming mode and a low-voltage Serial Programming mode A Watchdog Reset will leave this bit unchanged.
A sine wave generator with The Wt90s2323 supports arithmetic and logic functions between registers or between a con- stant and a register. If edge or toggle interrupt is selected, pulses that last longer than one clock Direct Data Addressing A bit This section describes the different addressing modes supported by the AVR architecture.

Memory instruction description on page The program memory is accessed with a two-stage pipeline. See page 12 for the different addressing modes. In the figures, OP means the operation code part of the instruction word. All other trademarks are the property of their respective owners. The 15 MSBs select word address Otherwise, the Watchdog will not be disabled.
Page 55 Figure Watchdog Oscillator Frequency vs. When using register indirect addressing modes with automatic pre-decrement and post- increment, the address registers X, Y, and Z are used and decremented and incremented. Bit 7 — Res:
