I have attached a picture of a folded cascode amplifier with class AB push pull stage.

My question is regarding the SLEW time of the amplifier. During the 'internal slewing' when the compensation capacitors CM1, CM2 are being charged up, what is the status of the M4, M4C, M8A, M9A, M2C, M6 ? Do these mosfets operate in saturation or triode region during the internal slewing ?

Will appreciate a suitable explanation.
