MTSR – Move to System Register
Architecture revision:
Architecture revision1 and higher.
Description
The instruction copies the value in the specified register to the specified system register. Note
that special timing concerns must be considered when operating on the system registers, see
the Implementation Manual for details.
Operation:
I.
Syntax:
I.
Operands:
I.
Status Flags:
Opcode:
Note:
Some system registers are implementation defined. If writing a system register that does not
exist, or to a register that is read only, the instruction is executed but no registers are updated.
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.
The instruction mtsr JOSP, Rx must be used with care. The programmer must ensure that no
change of flow instruction nor an INCJOSP instruction follows mtsr JOSP, Rx within a number of
instructions. This number of cycles is implementation defined. It should also be noted, that this is
true even if the instructions are not to be executed. For instance the sequence
