CC1312R: TCXO在CC1312上的使用，如何配置系统设置，才能使得CC1312能在睡眠和唤醒切换时功耗降到

Hi，

请参考以下工程师的答复：

It is described in this app note: https://www.ti.com/lit/an/swra640g/swra640g.pdf

And SysConfig actually configures everything, as long as you select the External 48Mhz TCXO in there:

Some additional information, as SysConfig does not configure everything, after all:

1. Once you have done the step I described above, copy the code from the application note I sent to a file in your project (rfPacketTx.c for instance), and replace GPIO_TCXO_PIN by CONFIG_GPIO_TCXO.

void Power_enableTCXO(bool turnOn)
{
    if ( turnOn ) {
        // Set corresponding DIO high to enable the TCXO
        GPIO_write(CONFIG_GPIO_TCXO, 1);
    }
    else {
        // Set the corresponding DIO low to disable the TCXO
        GPIO_write(CONFIG_GPIO_TCXO, 0);
    }
}

2. Then, in SysConfig, in the "Power" section, enter the name of the function you copied into "Enable TCXO Function":

3. Now, define the GPIO that powers the TCXO in SysConfig (DIO30 on the Launchpad)

4. Your project is ready to be compiled and flashed. Now, you should observe the same thing I do on an oscilloscope:

where green is DIO30, the GPIO that powers the TCXO, and yellow is the TCXO output.

Let me know how it works for you.
