MFDR – Move from Debug Register
Architecture revision:
Architecture revision1 and higher.
Description
The instruction copies the value in the specified debug register to the specified register in the
register file. Note that special timing concerns must be considered when operating on the debug
registers, see the Pipeline Chapter for details.
Operation:
I.
Syntax:
I.
Operands:
I.
Status Flags:
Opcode:
Note:
Debug registers are implementation defined. If accessing a debug register that does not exist,
the result is UNDEFINED.
This instruction can only be executed in a privileged mode. Execution from any other mode will
trigger a Privilege Violation exception.
