CC1101睡眠问题：想降低系统功耗，打算采用定时睡眠唤醒的模式 ，但是现在好像进不去睡眠模式

我运行了这两条指令：

CC1101_SET_CSN_HIGH( );
CC1101_Write_Cmd(CC1101_SPWD);

但是进不去睡眠模式，请问还应该配置其他的地方么？

你可以参考simpliciTI代码中关于sleep和wakeup的操作

{
bspIState_t s;

/* Critical section necessary for watertight testing and
* setting of state variables.

BSP_ENTER_CRITICAL_SECTION(s);

/* If radio is not asleep, put it to sleep */
if(mrfiRadioState != MRFI_RADIO_STATE_OFF)
{
/* go to idle so radio is in a known state before sleeping */
MRFI_RxIdle();

mrfiSpiCmdStrobe( SPWD );

/* Our new state is OFF */
mrfiRadioState = MRFI_RADIO_STATE_OFF;
}

BSP_EXIT_CRITICAL_SECTION(s);
}

/**************************************************************************************************

}

MRFI_SPI_DRIVE_CSN_LOW();

/* wait for MISO to go high indicating the oscillator is stable */
while (MRFI_SPI_SO_IS_HIGH());

/* wakeup is complete, drive CSn high and continue */
MRFI_SPI_DRIVE_CSN_HIGH();

/*
