current if the pull-up resistors are activated. The Port D pins are tri-stated when a reset
condition becomes active, even if the clock is not active.
Port D also serves the functions of various special features of the AT90S8515 as listed
on page 73.
Reset input. A low level on this pin for more than 50 ns will generate a reset, even if the
clock is not running. Shorter pulses are not guaranteed to generate a reset.
Input to the inverting oscillator amplifier and input to the internal clock operating circuit.
Output from the inverting oscillator amplifier.
ICP is the input pin for the Timer/Counter1 Input Capture function.
OC1B is the output pin for the Timer/Counter1 Output CompareB function.
ALE is the Address Latch Enable used when the External Memory is enabled. The ALE
strobe is used to latch the low-order address (8 bits) into an address latch during the first
access cycle, and the AD0 - 7 pins are used for data during the second access cycle.

In the different addressing modes these address registers have functions as fixed dis-
placement, automatic increment and decrement (see the descriptions for the different
instructions).
ALU – Arithmetic Logic
Unit
The high-performance AVR ALU operates in direct connection with all the 32 general-
purpose working registers. Within a single clock cycle, ALU operations between regis-
ters in the register file are executed. The ALU operations are divided into three main
categories: arithmetic, logical and bit functions.
In-System Programmable
Flash Program Memory
The AT90S8515 contains 8K bytes On-chip In-System Programmable Flash memory for
program storage. Since all instructions are 16- or 32-bit words, the Flash is organized as
4K x 16. The Flash memory has an endurance of at least 1000 write/erase cycles. The
AT90S8515 Program Counter (PC) is 12 bits wide, thus addressing the 4096 program
memory addresses.
See page 86 for a detailed description of Flash data downloading.
See page 13 for the different program memory addressing modes.
