Hello again I have noted that OR1200 use l.mfspr, l.mtspr and l.nop opcodes that are different from those given in OR1000 Architecture Manual and OR1200 IP Core Specification (see source code: or1200_ctrl.v). Is this meaningful or accidental? -- To unsubscribe from openrisc mailing list please visit http://www.opencores.org/mailinglists.shtml
