4.6
When accessing word data or longword data, the H8/3029 regards the lowest address bit as 0. The
stack should always be accessed by word access or longword access, and the value of the stack
pointer (SP, ER7) should always be kept even.
Use the following instructions to save registers:
Use the following instructions to restore registers:
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.
