| <dt><em>Description</em>:</dt> |
| <dd><p><code>IBITS</code> extracts a field of length <var>LEN</var> from <var>I</var>, |
| starting from bit position <var>POS</var> and extending left for <var>LEN</var> |
| bits. The result is right-justified and the remaining bits are |
| zeroed. The value of <code>POS+LEN</code> must be less than or equal to the |
| value <code>BIT_SIZE(I)</code>. |
