| <dt><code>-mmcu</code></dt> |
| <dd><p>selects the mcu architecture. If the architecture is 430Xv2 then this |

| </p> |
| </dd> |
| <dt><code>-mcpu</code></dt> |
| <dd><p>selects the cpu architecture. If the architecture is 430Xv2 then this |
| also enables NOP generation unless the <samp>-mN</samp> is also specified. |
| </p> |
| </dd> |
| <dt><code>-mP</code></dt> |

| </p> |
| </dd> |
| <dt><code>-mQ</code></dt> |
| <dd><p>enables relaxation at assembly time. DANGEROUS! |
| </p> |
| </dd> |
| <dt><code>-ml</code></dt> |
| <dd><p>indicates that the input uses the large code model. |
| </p> |
| </dd> |
| <dt><code>-mn</code></dt> |
| <dd><p>enables the generation of a NOP instruction following any instruction |
| that might change the interrupts enabled/disabled state. The |
| pipelined nature of the MSP430 core means that any instruction that |
| changes the interrupt state (<code>EINT</code>, <code>DINT</code>, <code>BIC #8, |
| SR</code>, <code>BIS #8, SR</code> or <code>MOV.W <>, SR</code>) must be |
| followed by a NOP instruction in order to ensure the correct |
| processing of interrupts. By default it is up to the programmer to |
| supply these NOP instructions, but this command line option enables |
| the automatic insertion by the assembler, if they are missing. |
| </p> |
| </dd> |
| <dt><code>-mN</code></dt> |
| <dd><p>disables the generation of a NOP instruction following any instruction |
| that might change the interrupts enabled/disabled state. This is the |
| default behaviour. |
| </p> |
| </dd> |
| <dt><code>-my</code></dt> |
| <dd><p>tells the assembler to generate a warning message if a NOP does not |
| immediately forllow an instruction that enables or disables |
| interrupts. This is the default. |
| </p> |
| <p>Note that this option can be stacked with the <samp>-mn</samp> option so |
| that the assembler will both warn about missing NOP instructions and |
| then insert them automatically. |
| </p> |
| </dd> |
| <dt><code>-mY</code></dt> |
| <dd><p>disables warnings about missing NOP instructions. |
| </p> |
| </dd> |
| <dt><code>-md</code></dt> |
| <dd><p>mark the object file as one that requires data to copied from ROM to |
| RAM at execution startup. Disabled by default. |
