Will set the system clock division available in the MEGA chips.

Var

| valign="top" width="100%" style="width: 489px; border: 1px solid rgb(0, 0, 0);" |
Variable or numeric constant that sets the clock division. Valid values are from 2-129.

 

A value of 0 will disable the division.

|}
</div>
 

On the MEGA 103 and 603 the system clock frequency can be divided so you can save power for instance. A value of 0 will disable the clock divider. The divider can divide from 2 to 127. So the other valid values are from 2 - 127.

 

Some routines that rely on the system clock will not work proper anymore when you use the divider. WAITMS for example will take twice the time when you use a value of 2.
