I need to use 'wait' instruction with WC field equal 1. Opcode of the instruction according to
EREF 2.0: A Programmer’s Reference Manual for Freescale Power Architecture® Processors
and Power ISA™ Version 2.07
shall be: 0x7C20007C
But I'm getting program exception. Only when I use 0x7C00007C (wait with WC=0), no exception is generated.
Documents above read that if some WC other than 0 is not implemented, bahaviour of the instruction should equal to the one with WC = 0.
I'd like to ask if the instruction (wait with WC=1) is really not implemented or if I do something wrong.
Thank you in advance
