TIMER0 is an 8 bit counter. See the hardware description of TIMER0.

 

When configured as a COUNTER:
<div style="padding: 0px; margin: 0px 0px 0px 4px;">
{| width="604" cellspacing="0" cellpadding="1" border="1" style="border: 2px solid rgb(0, 0, 0); border-spacing: 0px; border-collapse: collapse;"
|- style="vertical-align: top;"
| valign="top" width="21%" style="width: 123px; border: 1px solid rgb(0, 0, 0);" |
EDGE

| valign="top" width="100%" style="width: 472px; border: 1px solid rgb(0, 0, 0);" |
You can select whether the TIMER will count on the falling or rising edge.

|}
</div>
 

 

When configured as a TIMER:
<div style="padding: 0px; margin: 0px 0px 0px 4px;">
{| width="604" cellspacing="0" cellpadding="1" border="1" style="border: 2px solid rgb(0, 0, 0); border-spacing: 0px; border-collapse: collapse;"
|- style="vertical-align: top;"
| valign="top" width="17%" style="width: 99px; border: 1px solid rgb(0, 0, 0);" |
PRESCALE

| valign="top" width="100%" style="width: 496px; border: 1px solid rgb(0, 0, 0);" |
The TIMER is connected to the system clock in this case. You can select the division of the system clock with this parameter.

 

Valid values are 1 , 8, 64, 256 or 1024

|}
</div>
 

Note that some new AVR chips have different pre scale values. You can use these.

 

CONFIGURATION is optional. When you add configuration=mysetting, you can use this setting when you start the timer : START TIMER0 , mysetting

If you have multiple settings, you can start the timer with these different settings.

 

 

[[File:Notice.jpg|left|Notice.jpg]] Notice that the Help was written with the AT90S2313 and AT90S8515 timers in mind.

 

 

When you use the CONFIG TIMER0 statement, the mode is stored by the compiler and the TCCRO register is set.

When you use the STOP TIMER0 statement, the TIMER is stopped.

When you use the START TIMER0 statement, the TIMER TCCR0 register is loaded with the last value that was configured with the CONFIG TIMER0 statement.

 

 

So before using the [[START]] and [[STOP]] TIMER0 statements, use the CONFIG statement first.
