7.7.5 Bitwise Operators (Binary)
Syntax: Bitwise AND: <operand> & <operand>
Bitwise OR: <operand> | <operand>
Bitwise XOR: <operand> ^ <operand>
Description: The & (ampersand) operator performs an AND between the
two operands at the bit level.
The | (vertical bar) operator performs an OR between the two
operands at the bit level.
The ^ (caret) operator performs an XOR between the two
operands at the bit level.
The operands can be any expression evaluating to an absolute
expression.
Example:
$E & 3 ; = $2 (%1110 & %0011 = %0010)
$E | 3 ; = $F (%1110 | %0011 = %1111)
$E ^ 3 ; = $D (%1110 ^ %0011 = %1101)
7.7.6 Bitwise Operators (Unary)
Syntax: One’s complement: ~<operand>
Description: The ~ (tilde) operator evaluates the one’s complement of the
operand.
The operand can be any expression evaluating to an absolute
expression.
Example:
~$C ; = $FFFFFFF3 (~%00000000 00000000 00000000 00001100
=%11111111 11111111 11111111 11110011)
