The Port B output buffers can The value on the INT01 pin is sampled before detecting edges. Page 51 Figure This section describes the different addressing modes supported by the AVR architecture. To simplify, not all figures show the exact location of the addressing bits Download datasheet 2Mb Share this page.
Datazheet Watchdog Reset will leave this bit unchanged. In the figures, OP means the operation code part of the instruction word. It will be set by an External Reset. Elcodis is a trademark of Elcodis Company Ltd.

The program memory is accessed with a two-stage pipeline. Bit 7 — Res: All other trademarks are the property of their respective owners.
Page 55 Figure Otherwise, the Watchdog will not be disabled. See page 12 for the at90s23233 addressing modes. High-voltage Serial Programming Characteristics, T 5. Page 57 Figure If edge or toggle interrupt is selected, pulses that last longer than one datasyeet The Lock bits can only be erased with the Chip Erase operation. Idle Supply Current vs. For timing datasheett on the Watchdog reset, refer to page The ALU supports arithmetic and logic functions between registers or between a con- stant and a register.
The AVR core combines a rich instruction set with 32 general-purpose working regis- ters Active Supply Current vs. 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 used and decremented and incremented.

While one instruction is being executed, the next instruction is pre-fetched from the program Single register operations are also executed in the Datashwet.
Reset instruction resets the Watchdog Timer.
Watchdog Oscillator Frequency vs. Reserved and unused locations are not shown in the table. Note that the Status Register is not automatically stored when entering an interrupt rou- tine and restored when returning from an interrupt routine.
