CC1110 pm3 唤醒不能发送数据

HI:

          我在用cc1110做一个项目，要做到超低功耗。芯片pm3睡眠。外部io p1.中断唤醒。按照DN106上面做的 在休眠前切换晶振。开启io口中断。唤醒过后切换回hs xosc 但是不能发送数据。有遇到同样的问题的吗？

SLEEP &= ~0x04;
// Wait until [HS RCOSC] is stable (SLEEP.HFRC_STB = 1)
while ( ! (SLEEP & 0x20) );
// Switch system clock source to HS RCOSC (CLKCON.OSC = 1),
// and set max CPU clock speed (CLKCON.CLKSPD = 1).

CLKCON = (CLKCON & ~0x07) | 0x40 | 0x01;

// Wait until system clock source has actually changed (CLKCON.OSC = 1)
while ( !(CLKCON & 0x40) );
// Power down [HS XOSC] (SLEEP.OSC_PD = 1)
SLEEP |= 0x04;

}

切换回 XOSC 后有做Calibration 吗？

如何做校正？请指教

例程里面 Tx 发送那个函数里面应该有。也是一个 Strobe Command。

HI：我按照你说的加了如下的代码

SIDLE();
SCAL();

/while (MARCSTATE != MARCSTATE_IDLE); // Wait for calibration to complete

但是唤醒过后还是不能正常数据，请问是否还有其他原因？

不能正常发的现象具体是怎样的？射频口有信号出来吗？还是不能进入发送状态？有信号出来可以用示波器看看频率是不是有问题。
