PUSH (PUSH data)
Operation
ERn
Assembly-Language Format
PUSH.L ERn
Operand Size
Longword
Description
This instruction pushes data from a 32-bit register ERn onto the stack, tests the saved data, and
sets condition-code flags according to the result.
Available Registers
ERn: ER0 to ER7
Operand Format and Number of States Required for Execution
Notes
1. PUSH.L ERn is identical to MOV.L ERn, @–SP.
2. When PUSH.L ER7 is executed, the value saved on the stack is the ER7 value after effective
