MFSR – Move from System Register
Architecture revision:
Architecture revision1 and higher.
Description
The instruction copies the value in the specified system register to the specified register in the
register file. Note that special timing concerns must be considered when operating on the sys-
tem registers, see the Pipeline Chapter for details.
Operation:
I.
Syntax:
I.
Operands:
I.
Status Flags:
Opcode:
Note:
Some system registers are implementation defined. If accessing a system register that does not
exist, the result is UNDEFINED.
With the exception of accessing the JECR and JOSP system registers, this instruction can only
be executed in a privileged mode. Execution from any other mode will trigger a Privilege Viola-
tion exception.
JECR and JOSP can be accessed from all modes with this instruction.
