BA POPR Pop Registers |
|
Description |
The contents of registers whose number corresponds to set bits in the mask operand are replaced by longwords popped from the stack. R[n] is replaced if mask <n> is set. The mask is scanned from bit 0 to bit 14. Bit 15 is ignored. |
|
Notes |
This instruction is similar to the sequence MOVL (SP)+,RO MOVL (SP)+,R1 … MOVL (SP)+,R14 where only the masked registers are popped. |
