| |
| <p><a name="index-Macros_002c-MSP-430-1739"></a><a name="index-MSP-430-macros-1740"></a>The macro syntax used on the MSP 430 is like that described in the MSP |
| 430 Family Assembler Specification. Normal <code>as</code> |
| macros should still work. |
| |
| <p>Additional built-in macros are: |
| |
| <dl> |
| <dt><code>llo(exp)</code><dd>Extracts least significant word from 32-bit expression 'exp'. |
| |
| <br><dt><code>lhi(exp)</code><dd>Extracts most significant word from 32-bit expression 'exp'. |
| |
| <br><dt><code>hlo(exp)</code><dd>Extracts 3rd word from 64-bit expression 'exp'. |
| |
| <br><dt><code>hhi(exp)</code><dd>Extracts 4rd word from 64-bit expression 'exp'. |
| |
| </dl> |
| |
| <p>They normally being used as an immediate source operand. |
| <pre class="smallexample"> mov #llo(1), r10 ; == mov #1, r10 |
| mov #lhi(1), r10 ; == mov #0, r10 |
| </pre> |
