Bit-by-bit logic operator Meaning
B_AND
Bit-by-bit AND
B_OR
Bit-by-bit OR
B_NOT
Bit-by-bit negation
B_XOR
Bit-by-bit exclusive OR
Note
In arithmetic expressions, the execution order of all the operators can be specified by
parentheses, in order to override the normal priority rules.
Note
Spaces must be left between BOOLEAN operands and operators.
Note
The operator B_NOT only refers to one operand. This is located after the operator.
Examples
Example 1: Comparison operators
IF R10>=100 GOTOF DEST
or
R11=R10>=100
IF R11 GOTOF DEST
The result of the R10>=100 comparison is first buffered in R11.
Example 2: Logic operators
IF (R10<50) AND ($AA_IM[X]>=17.5) GOTOF DESTINATION
or
IF NOT R10 GOTOB START
NOT only refers to one operand.
Example 3: Bit-by-bit logic operators
IF $MC_RESET_MODE_MASK B_AND 'B10000' GOTOF ACT_PLANE
