+;                        MSP430 CODE EXAMPLE DISCLAIMER
+; 
+;  MSP430 code examples are self-contained low-level programs that typically
+;  demonstrate a single peripheral function or device feature in a highly
+;  concise manner. For this the code may rely on the device's power-on default
+;  register values and settings such as the clock configuration and care must
+;  be taken when combining code from several examples to avoid potential side
+;  effects. Also see www.ti.com/grace for a GUI- and www.ti.com/msp430ware
+;  for an API functional library-approach to peripheral configuration.

+;   MSP430F20x3 Demo - SD16A, Sample A1+ Continuously, Set P1.0 if > 0.3V
+;
+;   Description: A continuous single-ended sample is made on A1+ using internal
+;   VREf. Unipolar output format used.
+;   Inside of SD16 ISR, if A1 > 1/2VRef (0.3V), P1.0 set, else reset.
+;   ACLK = n/a, MCLK = SMCLK = SD16CLK = default DCO
