5.9
When performing stack-manipulating access, this LSI assumes that the lowest address bit is 0. The
stack should always be accessed by a word transfer instruction or a 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)
Performing stack manipulation while SP is set to an odd value leads to an address error. Figure 5.4
shows an example of operation when the SP value is odd.
