#if 1 #endif 的用法 怎么判斷進(jìn)入#if 1 還是#if 0 麻煩各路高手分析了
RSTSTAT = 0x00; //set watchdog duration4096ms
InitVariable();//Initial System
bBaudOption= 1;// 19200
bChanOption = 1;// vincom :290KHz
bModeOption = 0;// NBSF
bACFreqDetect = 0;// disable AC Detect
#if 1
if ((P1&0x04)==0x04) // P1.2 bModeOption,1:DMZC,0:NBSF
bModeOption = 0;
else
bModeOption = 1;
#endif
// Options for S1 switch
#if 0
if ((P0&0x10)==0x10) // P0.4 bBaudOption
bBaudOption = 1;
else
bBaudOption = 0;

bChanOption = 1;
else
