MTDR – Move to Debug Register
Architecture revision:
Architecture revision1 and higher.
Description
The instruction copies the value in the specified register to the specified debug register. Note
that special timing concerns must be considered when operating on the system registers, see
the Pipeline Chapter for details.
Operation:
I.
Syntax:
I.
Operands:
I.
Status Flags:
Opcode:
Note:
The debug registers are implementation defined, and updates of these registers are handled in
an implementation specific way.
This instruction can only be executed in a privileged mode. Execution from any other mode will
trigger a Privilege Violation exception.
