如何開啟A7159 DSSS Mode(直接序列展頻)功能
1. 初始化RF後，呼叫DSSS_MODE()函數，即可開啟DSSS展頻
void DSSS_MODE(void)
{
A7159_WritePageA(CODE_PAGEA, 0x1506); //PML=3bytes, IDL=2bytes
//DSSS mode : Preamble Length=3bytes
//IDL[1:0]=[x0], x=don't care, ID Length=1byte
//IDL[1:0]=[x1], x=don't care, ID Length=2bytes
A7159_WritePageB(DC_SHIFT_PAGEB, A7159Config_PageB[DC_SHIFT_PAGEB] | 0x0400); //DSSS mode : Preamble detect=2bytes
A7159_WritePageB(DSSS_PAGEB, A7159Config_PageB[DSSS_PAGEB] | 0xC4FF); //DSSS setting : ETHM=3, DSSS_SEL=1, FSYNC_D=255
A7159_WritePageB(DSSS2_PAGEB, A7159Config_PageB[DSSS2_PAGEB] | 0x6200); //TCNT_SEL=1, TCNT=34
A7159_WritePageB(SYN_PAGEB, A7159Config_PageB[SYN_PAGEB] | 0x0400); //enable DSSS=1
}
