However, the following registers have canonical names that must be used instead: <dl> <dt><code>r54</code><dd>sp <br><dt><code>r55</code><dd>lr <br><dt><code>r56</code><dd>sn <br><dt><code>r57</code><dd>idn0 <br><dt><code>r58</code><dd>idn1 <br><dt><code>r59</code><dd>udn0 <br><dt><code>r60</code><dd>udn1 <br><dt><code>r61</code><dd>udn2 <br><dt><code>r62</code><dd>udn3 <br><dt><code>r63</code><dd>zero </dl> <p>The assembler will emit a warning if a numeric name is used instead of the canonical name. The <code>.no_require_canonical_reg_names</code> assembler pseudo-op turns off this warning. <code>.require_canonical_reg_names</code> turns it back on. </body></html>
