74<p>When configured for debugging the Atmel AVR, <small>GDB</small> supports the
75following AVR-specific commands:
76</p>
77<dl compact="compact">
78<dt><code>info io_registers</code></dt>

80<a name="index-I_002fO-registers-_0028Atmel-AVR_0029"></a>
81<p>This command displays information about the AVR I/O registers.  For
82each register, <small>GDB</small> prints its number and value.
