On my clock (EndRun, not Garmin) the PPS is low true, so the rising edge is NOT the assert, but the rising edge at the end of the pulse. There is a difference between leading and rising. (I had to talk to an engineer at EndRun to confirm this was the case and it may not be for the Garmin.) For EndRun, flag2 is 1. -- R.
