Action
Will set the system clock division available in the MEGA chips.
Syntax
CLOCKDIVISON = var
Remarks
|
Var |
Variable or numeric constant that sets the clock division. Valid values are from 2-129.
A value of 0 will disable the division. |
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.
Most new processors support a limited number of division factors which can be selected using CONFIG CLOCKDIV.

Example
$regfile = "m103def.dat" ' specify the used micro $crystal = 8000000 ' used crystal frequency $baud = 19200 ' use baud rate $hwstack = 32 ' default use 32 for the hardware stack $swstack = 10 ' default use 10 for the SW stack $framesize = 40 ' default use 40 for the frame space Config Com1 = Dummy , Synchrone = 0 , Parity = None , Stopbits = 1 , Databits = 8 , Clockpol = 0 Clockdivision = 2
