By default all interrupts are disabled.

To disable all interrupts specify INTERRUPTS.

<span style="font-family: Arial;"> </span>

To enable the enabling and disabling of individual interrupts use ENABLE INTERRUPTS.

The ENABLE INTERRUPTS serves as a master switch. It must be enabled/set in order for the individual interrupts to work.

<span style="font-family: Arial;"> </span>

The interrupts that are available will depend on the used microprocessor. The available interrupts are shown automatically in the editor.

 

 

[[File:Notice.jpg|left|Notice.jpg]] To disable the JTAG you can use DISABLED JTAG. The JTAG is not an interrupt but a device.
