+;                        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.

+;   MSP430F20x1 Demo - Comp_A, Simple 2.2V Low Battery Detect
+;
+;   Description: Two comparator_A reference generators 0.25*Vcc and ~ 0.55V
+;   are compared for a simple battery check of 2.2V. In the subroutine
+;   Batt_Check a small capacitor that must be added to P2.3 is first charged
+;   to 0.25*Vcc and then compared to ~ 0.55V. If 0.25*Vcc,
+;   is above ~0.55V, P1.0 is toggled, else set. Batt_Check is
+;   called constantly in an endless loop - in an actual application,
+;   Batt_Check should be called very infrequently to save power.
+;   ACLK = n/a, MCLK = SMCLK = default DCO
+;
+;   There is a tolerence of the Comp_A reference generator and in the
+;   device specific datasheet. In most applications, the tolerence of the
+;   reference generator is more than adequate to detect Low Battery.
