Action

Will set the system clock division available in some 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
