Stepper motor current, peak or RMS?

I was reading the specification of 6HC and am trying to understand the peak vs RMS stepper current rating.

"6 High Current Trinamic 5160 stepper drivers running at up to 4.45A RMS, 6.3A peak with firmware control of the full feature set including up to 256 microstepping, StallGuard 2 and StealthChop2"

If we use M906 to set a peak current of 6.3A and the motor stops at a peak current microstep, will this result in a 6.3A DC current (=6.3A RMS) which is beyond the driver's spec?

When a stepper vendor specifes the max motor current, is this typically peak or RMS? E.g. this is what StepperOnline say
