Assembly-Language Format
STM.L <register list>, @–SP
Operand Size
Longword
Description
This instruction saves a group of registers specified by a register list onto the stack. The registers
are saved in ascending order of register number.
Two, three, or four registers can be saved by one STM instruction. The following ranges can be
specified in the register list.
Two registers: ER0–ER1, ER2–ER3, ER4–ER5, or ER6–ER7
Three registers: ER0–ER2 or ER4–ER6
Four registers: ER0–ER3 or ER4–ER7
Available Registers
ERn: ER0 to ER7
