CC1101 with MS430F5529

Hi,

I am trying to interface CC1101 with MSP430F5529. After writing SIDLE when I am checking TI_CC1101_MARCSTATE register to be idle, it is never becoming IDLE(0x01) or able to enter into RX state(RX). 

Please find below code snippets attached.

Please help me.

Please

UCHAR8_t ucChannelNo;

for(ucChannelNo=0; ucChannelNo < MAX_CHANNEL; ucChannelNo++)
{
REFRESH_WDT;
/*Set to Manual Calibration*/
TI_CC_SPIWriteReg(TI_CC1101_MCSM0 , 0x08); //MainRadio Cntrl State Machine
/*since forced calib can be performed only from idle mode.*/
TI_CC_SPIStrobe(TI_CC1101_SIDLE);

if(TI_CC_SPIReadStatus(TI_CC1101_MARCSTATE) == TX)
{

}
