用单片机实现(载波监听/冲突检测)的功能

/**************************************************
 *
 * Intrinsic functions for the MSP430 IAR Systems C/C++ Compiler
 * provided for backward compatibility with version 1 of the compiler.
 *
 * Most intrincis functions have been replaced with equivalent
 * intrinsic functions that follow the current naming convention.
 * However, there are two exceptions:
 *
 * 1) The intrinsic functions _BIx_SR and _BIx_SR_IRQ are replaced
 *    with __bix_SR_register and __bix_SR_register_on_exit. The new
 *    intrinsic functions no longer returns the previous value of the
 *    status register. You can access that value by using the
 *    intrinsic function __get_SR_register.
 *
 * 2) The intrinsic function _BIS_NMI_IE1 has been replaced with the
 *    #pragma directive bis_nmi_ie1. The reason why this no longer is
 *    an intrinsic function is that the effect was always performed,
 *    even if the intrinsic was guarded with, say, an "if"-statement.
