In most cases, it is efficient to initialize the user stack which is allowed to grow (downwards) until it reaches
the address 270h (26Fh32h=23Eh). Thus, the resulting size of the maximum user stack is 16Dh
(3DCh272h=16Ah) on the MSP430x325 family and 360h (5DCh272h = 36Ah) on the MSP430x33x family.
