A.1.1 Boolean Variables
A Boolean variable stores the status (either 1 or 0) of one bit. When a bit has a value of
1, it is said to be on and logically true. When a bit has a value of 0, it is said to be off
and logically false.
You can reference an individual bit using any of these methods:
Method Example
