Logical Instructions
The logical instructions perform bit-wise logical operations on individual
words.
Using Logical
Instructions
When using logical instructions, observe the following:
• Source and Destination must be of the same data size (i.e. all words
or all long words).
• Source A and Source B can be a constant or an address, but both
cannot be constants.
• Valid constants are -32768 to 32767 (word) and -2,147,483,648 to
2,147,483,647 (long word).
Instruction Used To: Page
AND - Bit-Wise AND Perform an AND operation 213
OR - Logical OR Perform an inclusive OR operation 214
XOR - Exclusive OR Perform an Exclusive Or operation 215
NOT - Logical NOT Perform a NOT operation 216
IMPORTANT
Do not use the High Speed Counter Accumulator
(HSC.ACC) for the Destination parameter in the AND,
OR, and XOR instructions.
