* 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.

// MSP430FR413x Demo - LCD_E, Display "123456" and blink in LPM3.5 mode.
//
// Description: Displays "123456" in sequence to the LCD display.
// f(LCD) = 32768Hz/((7+1)*64) = 256Hz,
// f(BLINK) = f(LCD)/((3+1)*64) = 1Hz.
// MSP430 works in LPM3.5 mode for ultra low power.
// ACLK = default REFO ~32768Hz,
// MCLK = SMCLK = default DCODIV ~1MHz.
