It's been a while since I was an ATR pilot, but here it goes:

PL= Power Lever
CL= Condition Lever (Fuel)
NH= High Pressure section
NL= Low Pressure section
NP= Propellar RPM

NH is basically the N1
NL is N2

Oh yeah, motor number 2 has a prop brake. It allows the gas generator to operate without having to have the prop spin. It's prone to catching on fire if you set the prop brake above NP limits. So don't do that.
