Errata: Typos in the example on page 194

**Chapter:** 9 (page 194)
**Description:**
In the example, the enable flag is calculated to be shifted 2 * 2 = 4 bits, but in the visualization, it is shifted 6 bits.
```
Enable flag:    00000000 00000000 00000000 01000000
```
should be
```
Enable flag:    00000000 00000000 00000000 00010000
```
In the same page, the other visualizations depending on the enable flag have enable bit typos.
