Notes on Use of the Stack
When accessing word data or longword data, the chip assumes that the lowest address bit is 0. The
stack should always be accessed by word transfer instruction or longword transfer instruction, and
the value of the stack pointer (SP: ER7) should always be kept even. Use the following
instructions to save registers:
PUSH.W Rn
(or MOV.W Rn, @-SP)
PUSH.L ERn (or MOV.L ERn, @-SP)
Use the following instructions to restore registers:
POP.W
Rn
(or MOV.W @SP+, Rn)
POP.L
ERn (or MOV.L @SP+, ERn)
Setting SP to an odd value may lead to a malfunction. Figure 4.6 shows an example of what
happens when the SP value is odd.

CCR: Condition-code register

R1L: General register R1L

Note: This diagram illustrates an example in which the interrupt control mode is 0, in advanced
mode.
