<h5 class="subsubsection">9.8.2.4 Register Names</h5>
<p><a name="index-D10V-registers-737"></a><a name="index-registers_002c-D10V-738"></a>You can use the predefined symbols <span class="samp">r0</span> through <span class="samp">r15</span> to refer to the D10V
registers. You can also use <span class="samp">sp</span> as an alias for <span class="samp">r15</span>. The accumulators
are <span class="samp">a0</span> and <span class="samp">a1</span>. There are special register-pair names that may
optionally be used in opcodes that require even-numbered registers. Register names are
not case sensitive.
<p>Register Pairs
<dl>
<dt><code>r0-r1</code><br><dt><code>r2-r3</code><br><dt><code>r4-r5</code><br><dt><code>r6-r7</code><br><dt><code>r8-r9</code><br><dt><code>r10-r11</code><br><dt><code>r12-r13</code><br><dt><code>r14-r15</code><dd></dl>
<p>The D10V also has predefined symbols for these control registers and status bits:
<dl>
<dt><code>psw</code><dd>Processor Status Word
<br><dt><code>bpsw</code><dd>Backup Processor Status Word
<br><dt><code>pc</code><dd>Program Counter
<br><dt><code>bpc</code><dd>Backup Program Counter
<br><dt><code>rpt_c</code><dd>Repeat Count
<br><dt><code>rpt_s</code><dd>Repeat Start address
<br><dt><code>rpt_e</code><dd>Repeat End address
<br><dt><code>mod_s</code><dd>Modulo Start address
<br><dt><code>mod_e</code><dd>Modulo End address
<br><dt><code>iba</code><dd>Instruction Break Address
<br><dt><code>f0</code><dd>Flag 0
<br><dt><code>f1</code><dd>Flag 1
<br><dt><code>c</code><dd>Carry flag
</dl>
