indicate that the bit is in the state that disables the function it controls. In all tables, the terms 0 and 1 are used to describe the actual value that should be written to the bit, or the value that it yields when read. The term status bit is used to describe a bit in a register that reflects a specific condition.

The status bit can be read by software to determine operational or exception conditions.
