STM – Store Multiple Registers
Architecture revision:
Architecture revision1 and higher.
Description
Stores the registers specified to the consecutive memory locations pointed to by Rp. Both regis-
ters in the register file and some of the special-purpose registers can be stored.
I.
Syntax:
I.
Operands:
I.
Status Flags:
Opcode:
Note:
Emtpy Reglist16 gives UNDEFINED result.
If Rp is in Reglist16 and pointer is written back the result is UNDEFINED
The R bit in the status register has no effect on this instruction.
