//  MSP430F21x2 Demo - Timer1_A2, Toggle P3.6/TA1_1, Up Mode, HF XTAL ACLK
//
//  Description: Toggle P3.6 using hardware TA0_1 output. Timer1_A2 is configured
//  for up mode with TA1CCR0 defining period. In this
//  example, TA1CCR0 is loaded with 500-1 and TA0_1 will toggle P3.6 at TA1CLK/500.
//  Thus the output frequency on P3.6 will be the TA1CLK/1000. No CPU or
//  software resources required.
//  ACLK = MCLK = TA1CLK = HF XTAL
//  //* HF XTAL REQUIRED AND NOT INSTALLED ON FET *//
//  //* Min Vcc required varies with MCLK frequency - refer to datasheet *//
//  As coded with TA1CLK = ACLK, P3.6 output frequency = HF XTAL/1000
