Specify MSR Reset Value:
Specifies reset value for select MSR bits.
- Setting ICE (
=0x0020) enables
instruction cache at reset.
- Setting DCE (
=0x0080) enables
data cache at reset.
- Setting EIP (
=0x0200) sets
exception in progress at reset.
- Setting EE (
=0x0100)
enables exceptions at reset.
- Setting BIP (
=0x0008) sets
break in progress at reset.
- Setting IE (
=0x0002)
enables interrupts at reset.
Tip: Enabling cache at reset allows execution to start immediately from external
memory and can thus be used to reduce or eliminate the need for LMB memory.
