// MSP430F21x2 Demo - Timer0_A3, Toggle P1.1/TA0_0, Up/Down Mode, HF XTAL ACLK
//
// Description: Toggle P1.1 using hardware TA0_0 output. Timer_A is configured
// for up/down mode with TA0CCR0 defining period, TA0_0 also output on P1.1.
// In this example, TA0CCR0 is loaded with 250 and TA0_0 will toggle P1.1 at
// TA0CLK/2*250. Thus the output frequency on P1.1 will be the TA0CLK/1000.
// No CPU or software resources required.
// ACLK = MCLK = TACLK = HF XTAL
// //* HF XTAL REQUIRED AND NOT INSTALLED ON FET *//
// //* Min Vcc required varies with MCLK frequency - refer to datasheet *//
// As coded with TA0CLK = ACLK, P1.1 output frequency = HF XTAL/1000
