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
