* 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.

// MSP430F20xx Demo - WDT+ Failsafe Clock, DCO SMCLK
|
|
//
|
|
// Description; Allow WDT+ in watchdog to timeout. Toggle P1.0 in main
|
|
// funnction. LPM4 is entered, this example will demonstrate WDT+ feature
|
|
// of preventing WDT+ clock to be disabled.
|
|
// The WDT+ will not allow active WDT+ clock to be disabled by software, the
|
|
// LED continues to Flash because the WDT times out normally even though
|
|
// software has attempted to disable WDT+ clock source.
|
|
// The MSP430F1xx will stop code execution when software disables WDT+ clock
|
|
// source.
|
|
// ACLK = n/a, MCLK = SMCLK = default DCO
