4.4
In word access, the least significant bit of the address is always assumed to be 0. The stack is
always accessed by word access. Care should be taken to keep an even value in the stack pointer
(general register R7). Use the PUSH and POP (or MOV.W Rn, @–SP and MOV.W @SP+, Rn)
instructions to push and pop registers on the stack.
Setting the stack pointer to an odd value can cause programs to crash. Figure 4.9 shows an
example of damage caused when the stack pointer contains an odd address.
