/********************************************************************
*
* Standard register and bit definitions for the Texas Instruments
* MSP430 microcontroller.
*
* This file supports assembler and C development for
* MSP430x31x devices.
*
* Texas Instruments, Version 2.1
*
* Rev. 1.1, Included <In430.h> rather than "In430.h"
*           Changed definition of LPM4 bits (device effect not changed)
*           Corrected LPMx_EXIT to reference new intrinsic _BIC_SR_IRQ
*           The file contents were reordered
*
* Rev. 1.2, Enclose all #define statements with parentheses
*
* Rev. 1.3, Added sfrb for TCDAT and TCPLD
*
* Rev. 1.4, Removed incorrect label 'BTRESET'
* 
* Rev. 2.1, Alignment of defintions in Users Guide and of version numbers
