//******************************************************************************
//  MSP430x11x1 Demo - Basic Clock, Output Buffered SMCLK, ACLK and MCLK/10
//
//  Description: Buffer ACLK on P2.0, default SMCLK(DCO) on P1.4 and MCLK/10 on
//  P1.1. To measure SMCLK on P1.4 with the FET, use "Release JTAG on Run"
//  in the debugger to have access to the port. Then run the code.
//  ACLK = LFXT1 = 32768, MCLK = SMCLK = default DCO ~800kHz
//  //* External watch crystal installed on XIN XOUT is required for ACLK *//	
//
