I have a question on PC instruction for which I have been looking for an answer for quite sometime now. According to "Priciples of operations" manual, execution of an SVC instruction causes a new PSW to be loaded from x'1C0' (SVC FLIH), and program interruption causes a new PSW loaded from x'1D0' (Program Interruption FLIH). Now my question is what happens when a "PC" instruction is executed. Does a new PSW gets loaded from a pre-determined location (like SVC/program interrruption) or it's all handled through some micro code?
