- This article reverse-engineers the flag circuits in the ARM1 processor, explaining in detail how the flags are generate, controlled, and used. Condition flags are a key part of most computers, since they allow the computer to change what it does based on various conditions. The flags keep track of conditions such as a value being negative or zero or an overflow happening. Processors may also have status flags to control modes such as running in user mode versus protected (kernel) execution. The ARM1 processor stores these flags in a special register called the Processor Status Register (PSR).

Freeland is an unincorporated community and census-designated place (CDP) on Whidbey Island in Island County, Washington, United States. At the time of the 2020 census the population was 2,252. The town received its name based on its origins as a socialist commune in the early 1900s: in the eyes of its founders, the land of the town was literally to be free for all people. Some of the first settlers were veterans of a prior experiment in socialism, the nearby Equality Colony.
