//  MSP430F22x4 Demo - Timer_A, Toggle P1.1/TA0, Up/Down Mode, HF XTAL ACLK
//
//  Description: Toggle P1.1 using hardware TA0 output. Timer_A is configured
//  for up/down mode with TACCR0 defining period, TA0 also output on P1.1.
//  In this example, TACCR0 is loaded with 250 and TA0 will toggle P1.1 at
//  TACLK/2*250. Thus the output frequency on P1.1 will be the TACLK/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 TACLK = ACLK, P1.1 output frequency = HF XTAL/1000
