... Description The AT90S4434/8535 is a low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. By executing pow- erful instructions in a single clock cycle, the AT90S4434/8535 achieves throughputs approaching 1 MIPS per MHz allowing the system designer to optimize power consumption versus processing speed.

... Port D pins that are externally pulled low will source current if the pull-up resistors are activated. Port D also serves the functions of various special features of the AT90S4434/8535 as listed on page 79. The Port D pins are tri-stated when a reset condition becomes active, even if the clock is not running. ...

... The ALU supports arithmetic and logic functions between registers or between a constant and a register. Single register operations are also executed in the ALU. Figure 2 shows the AT90S4434/8535 AVR RISC microcontroller architecture. In addition to the register operation, the conventional memory addressing modes can be used on the register file as well. ...
