Abstract
Set the Memory value to the most common control during firmware. This article describes the programming skills that are common when C statements are used for firmware, and correspond to each other with the image watermark.

Introduction
This article will discuss the following topics:

1. Set a bit counter to 1

2. Set a bit counter to 0

3. Toggle a bit (0 changes to and 0)

4. Determine whether a bit of a shard is 1

5. Determine whether a bit of a shard is 0

1. Set a bit counter to 1

C. Yan

 
Flag | = mask;

Or

 
Flag | = (1<N );

OpenGL

 
Flag [N] =1'B1;

2. Set a bit counter to 0

C. Yan

 
Flag & = ~ Mask;

Or

Flag & = ~ (1<N );

OpenGL

 
Flag [N] =1'B0;

3. Toggle a bit (0 changes to and 0)

C. Yan

 
Flag ^ = mask;

Or

 
Flag ^ = (1<N );

OpenGL

 
Flag [N] = ~ Flag [N];

4. Determine whether a bit of a shard is 1

C. Yan

 
If(Flag & Mask)

OpenGL

 
If(Flag [N])

5. Determine whether a bit of a shard is 0

C. Yan

 
If(! (Flag & Mask ))

OpenGL

 
If(~ Flag [N])
