谁能告诉我这些信号是啥意思? 手册只字未提。。。
Viki Shi:
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。。。

回复 WH HUANG:
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?
