CC1310 SYSGPOCTL 相关设置信息，哪里可以找到详细描述？

0h = CPE GPO line 0
1h = CPE GPO line 1
2h = CPE GPO line 2
3h = CPE GPO line 3
4h = MCE GPO line 0
5h = MCE GPO line 1
6h = MCE GPO line 2
7h = MCE GPO line 3
8h = RFE GPO line 0
9h = RFE GPO line 1
Ah = RFE GPO line 2
Bh = RFE GPO line 3
Ch = RAT GPO line 0
Dh = RAT GPO line 1
Eh = RAT GPO line 2
Fh = RAT GPO line 3

谁能告诉我这些信号是啥意思？ 手册只字未提。。。

手册上有啊， CPE/MCE/RFE/RAT分别是四个模块，手册上有具体介绍，以RAT为例：

The RAT module has four controllable outputs, RAT_GPO0 through RAT_GPO3. These signals may be controlled by one of the RAT channels and mapped to signals available for the IOC using the SYSGPOCTL register (see Section 23.8.2.9). The signal RAT_GPO0 is reserved for starting the transmitter and is controlled internally by the radio CPU (see Section 23.3.2.8). The other three signals may be configured using the CMD_SET_RAT_OUTPUT command (see Section 23.3.4.11). The different output modes decide the transition of the output when an interrupt occurs on the chosen RAT channel except for the always-0 and always-1 configurations, which take effect immediately and may be used for initialization.

这个我了解了，也只有这个有介绍。其它三个找找看，有没有都介绍了？ MCE GPO0-3,...手册里没有任何信息。。。

CPE: Command and Packet Engine.

The unit on the RF core that is responsible for command execution and packet encoding/decoding. It acts as a supervisor for all other sub-modules during command execution.

MCE: Modem Control Engine.

A functional unit on the RF core that sits in between the CPE and the RFE. It is responsible for signal modulation/demodulation and binary base band processing.

RAT: Radio Timer.

A functional unit on the RF core that provides accurate timing for command execution. It runs with 1/4 speed of the high- frequency oscillator.

RFE: Radio Front-end Engine.

A functional unit on the RF core that is responsible for the analog signal processing part. It connects the MCE to the antenna.

这些缩写我已经问过了，，，各位看客，你们懂得，这个些IO输信是啥信号吗？
