K2H12 Keystone II Reserved Pins

Greetings,

I've seen from previous posts for certain devices that people have noticed some of the Reserved pins being used in devkit schematics, and the explanation has been that they are useful internally and we should just ignore them, but that some might actually have some good use, or there is a requirement that one or two be grounded or shorted.

1. Are there any such Reserved pins in the K2H12?
2. I noticed that one of the pins, RSV012, is being labelled as a PLLLOCK signal. I also discovered that although there is no further information on RSV012 in the data manual, there *is* a mention of a PLLLOCK device pin: "PLL Lock Pin Control (PLLLOCK_PINCTL) Register This register controls the PLLLOCK mux and selects which PLL lock signals are routed to the PLLLOCK device pin." But there is no further explanation of where this PLLLOCK pin is, is it AK5 (RSV012) ? 

Thanks,

Justin
