;

OUTn

....

statename:

OutputMode ....

The possible output mode are listed and described on the following table. The maximum number of

output state are 256.

Output Mode

Description

X

Set OUTn to input mode with pull-high resistor

H

L

Set the output pins to logic low

where ²SirenOn² denotes the output statename. Executing ²SirenOn² in the path command will send

a positive pulse train to PB0 and send a logic low to PB1.

Path command definition

Syntax:

PATHS

pathname: path command ....

The pathname is defined according to the user¢s desire. The elements of the path command are listed

and described on the following table. Each path equation consists of many path commands and each
