Returns the specified PTPG output pin’s current delay value
Float — the PTPG delay in seconds
This method provides the current duration in seconds that a Pin-Triggered Pulse Generator output pin has been set to pause between being triggered and starting to count pulses.
The returned value can vary slightly from the value supplied to pin.configure() or [pin.write()](/api/hardware/pin/write/, due to hardware limitations. Typically, the returned value has been rounded to a whole number of clock cycles.
An exception will be thrown if this call is made to a pin that is not currently configured in PTPG mode.
