==Description==

[[Image:Synchronized_PWM_Child.PNG]]

A synchronized PWM child may have an independent duty cycle from the parent. Either choose the resource to reference, or provide the name of a resource by name, as defined by a PWM Output block. This is necessary when the parent pin is made calibratable. The Duty Cycle input is an int16, ranging from -4096 to 4096, where 0 is 0%, 4096 is 100%. When the value is negative the polarity is reversed, this is only valid on PWM resources that are H-Bridge outputs, like ETC or H1. Phase offset delays the phase input/4096% of the period. A phase offset of 0 will have it start at the same time as the parent and 2048 would have it be delayed half the period of the parent. When "Output Current" is checked, the drive current in milliamps is provided. When "Output Fault Status" is checked, a value indicating fault status is provided. This value is one of: 0 - OK, 1 - Fault, 2 - Indeterminate.

==Limitations==

This block currently only works for 5xx processor targets, each parent can only have two or fewer child PWMs, and the parent and child resources must reside on the same [../MotoHawk_topics/TPU.html TPU bank]. If the resource is not behaving as exspected there are a few common errors. To check the common errors look at the resource creation status in the display(System|Debug|Resources|PWM|"ResourceName").
