Using the UP mode: Write a C code that runs on the LaunchPad MSP430 and uses Timer_A in the continuous mode. Run the timer from ACLK and set it to the 12 KHz VLO (code shown below). Within the timer, adjust the clock signal so that is becomes 3,000 Hz. Our goal is to generate a delay of 0.5 seconds. How many cycles does this correspond to? When the duration of the timer elapses, toggle the RED LED, which is mapped to Port 1.0 and is active high.

Timer_A Elements: Channel 0

Event: TAR= TACCR0 (compare)

Bits: CCIE/CCIFG

Main register (16-bit): TACCR0

Configuration register (16-bit): TACCTL0

Vector: TIMERA0_VECTOR (single-source)

Configuration:

TASSEL = [1: ACLK]

ID = [0: divide by 1] [1: divide by 2] [2: divide by 4] [3: divide by 8]

Mode = [1: UP]

TACLR = [Clear TAR to zero]

TACCR0 = [TAR]

//Code that sets ACLK to VLO @ 12 kHz

BCSCTL1 &= ~XTS; //Set XTS=0

BCSCTL3 &= ~LFXT1S_3; //Clear LFXT1S

BCSCTL |= LFXT1S_2; // Set LFXT1S=2 (VLO)
