low power mode is restored (using GO). This behavior appears to
happen on all devices except the MSP430F12x.

A.2 Program Development (Assembler, C-Compiler, Linker)
1) The files supplied in the 430\tutor folder work only with the
simulator. Do not use the files with the FET. Refer to FAQ: Program
Development #11)
2) A common MSP430 “mistake” is to fail to disable the Watchdog
mechanism; the Watchdog is enabled by default, and it will reset the
device if not disabled or properly handled by your application. Refer to
FAQ, Program Development #14).
3) When adding source files to a project, do not add files that are
#include’ed by source files that have already been added to the
project (say, an .h file within a .c or .s43 file). These files will be added
to the project file hierarchy automatically.
4) In assembler, enclosing a string in double-quotes (“string”)
automatically appends a zero byte to the string (as an “End Of
String” marker). Enclosing a string in single-quotes (‘string’) does not.
5) When using the compiler or the assembler, if the last character of a
source line is backslash (\), the subsequent carriage return/line
feed is ignored (i.e., it is as if the current line and the next line are a
single line). When used in this way, the backslash character is a “Line
Continuation” character.
6) The linker output format must be “Debug info” or “Debug info
with terminal I/O” (.d43) for use with C-SPY. C-SPY will not start
otherwise, and a error message will be output. C-SPY cannot input a
.TXT file.
7) Position Independent code can be generated (using PROJECT-
>OPTIONS->GENERAL OPTIONS->TARGET->POSITION-
INDEPENDENT CODE).
8) Within the C libraries, GIE (Global Interrupt Enable) is disabled
before (and restored after) the hardware multiplier is used. Contact
TI if you wish the source code for these libraries so that this behavior
can be disabled.
