The halt opcode stops the pattern sequencer and burst, keeping pins at their programmed states. Place the halt on the last vector to prevent patterns from ending with undefined behavior.

Syntax Reference

Table 6. Syntax Description for the Halt Opcode
Syntax Description
halt Stops the execution of the pattern sequencer and the pattern burst. When the pattern sequencer halts, all the pins maintain their current programmed state.

The pattern sequencer does not automatically stop execution at the end of the pattern. You must specify the halt opcode on the last vector in the pattern to stop the execution of the pattern. Undefined behavior results in patterns that complete without a halt code.
