## Detailed Description

A Class that consumes CPU time on the Serial Wombat chip in order to facilitate testing.

This class is only supported on the Serial Wombat SW18AB chip. It is not supported on the Serial Wombat 4X line.

This class provides a means to consume throughput inside of a pin in order to test different CPU loading secenarios.

This class provides an array of 16 delays measured in uS. When each frame runs the cumulative frame counter is taken mod 16 to determine which delay to use. During this delay the pin goes high and waits in a loop for approximately the specified number of uS.
