Arithmetic operation
Operator Format Description
&
&
Calculates the logical product (AND) of each bit of and .
|
|
Calculates the logical sum (OR) of each bit of and .
^
^
Calculates the exclusive logical sum (XOR) of each bit of and .
~
~
Inverse the logic of each bits of .
For word devices and fixed values, 0 will be 65,535, and 65,535 will be 0.
For bit device, 0 will be 1, and 1 will be 0.
<<
<<
Shifts each bit of to the left for bit(s).
>>
>>
Shifts each bit of to the right for bit(s).
Function Format Description
Bit set
SET( );
Turns bit device to 1.
This is the same result as = 1;.
Bit reset
RST( );
Turns bit device to 0.
This is the same result as = 0;.
Bit reverse
REV( );
Reverses the 1 and 0 of bit device .
This is the same result as = ~ ;.
