• 本篇介紹A7130 WOR功能，關於什麼是Amiccom WOR之前很多篇都有介紹過了，這邊就不再贅述

• Demo Code<A7130-A01(A9108MCU) - WOR.zip>

"WOR_enable()" Function介紹:

1. 設定GIO1為WTR Mode(此pin可以在WOR時觀察Sleep & active的時間間隔)，設定GIO2為Wake up signal pin

2. 需關閉CRC Check
   

	A7130_WriteReg(GPIO1_REG, 0x01);	//GIO1 as WTR
	A7130_WriteReg(GPIO2_REG, 0x11);	//GIO2 as Wake up signal
	A7130_WriteReg(CODE1_REG,A7130Config[CODE1_REG]&0xEF); //Disable CRC

    3.設定Sleep & Active time，進入Standby mode

	A7130_WriteReg(RCOSC1_REG, 0x0A);	//setup WOR Sleep time and RX time
	A7130_WriteReg(RCOSC2_REG, 0x14);
	StrobeCmd(CMD_STBY);				//entry standby mode

    4.校準RC OSC

//RC Calibration
    RCOSC_Calibration();

    5.RC校準流程

Uint8 RCOSC_Calibration(void)
{
    Uint8 tmp, rcoc, rcot, retry;

    for(rcot = 0; rcot < 4; rcot++)
    {
        for(retry = 0; retry < 3; retry ++)
        {
            A7130_WriteReg(RCOSC3_REG, 0x00);                   // RC-OSC disable
            A7130_WriteReg(RCOSC3_REG, (0x04 | (rcot << 4)));   // RCOSC_E=1, CALW=0. RC-OSC enable (startup).
            rcoc = A7130_ReadReg(RCOSC1_REG);                   // read RCOC before calibration
            A7130_WriteReg(RCOSC3_REG, (0x0C | (rcot << 4)));   // RCOSC_E=1, CALW=1. RC-OSC calibration begin.

            do
            {
                tmp = A7130_ReadReg(RCOSC3_REG) & 0x08;
            } while(tmp);                                       // wait RC-OSC calibration finish.
            
            tmp = A7130_ReadReg(RCOSC1_REG);
            if(tmp != rcoc)                                     // check RCOC.
            {
                rcoc = tmp;
                if(rcoc >= 20)
                {
                    return 0;
                }
            }
        }
    }

    return 0xFF;
}

    6. WORE=1(Enable WOR)，Wait GIO2 Go high(表示Wake up 成功)

	A7130_WriteReg(MODECTRL_REG, A7130Config[MODECTRL_REG] | 0x08);	//WORE=1 to enable WOR function
	while(GIO2==0);		//Stay in WOR mode until receiving ID code(sync ok)

    7.WORE=0(Disable WOR)，& 調用RxPacket() Function 來Read RX Data Buffer

	A7130_WriteReg(MODECTRL_REG, A7130Config[MODECTRL_REG]);	//WORE=0 to disable WOR function
	RxPacket();
