In addition, some parameters can be enabled or disabled. This feature is evident by the color of the block parameter. For example, if the 
block parameter is dark blue, the parameter is enabled. If it is light grey, it is disabled. To enable or disable a parameter, click on it.

More direct changes to registers and bit fields can be made in the memory map, which is linked from the chip block diagram (Figure 7) 
through the “Proceed to Memory Map” button. In this view, names, addresses, and data can be manually altered by the user.
