23.3.4.11 CMD_SET_RAT_CPT: Set RAT Channel to Capture Mode
Command ID number: 0x0603
CMD_SET_RAT_CPT is an immediate command that takes the parameters listed in
Byte Index Field Name
0–1 commandNo
2–3 config
On reception, the radio CPU sets the RAT channel given by config.ratCh in capture mode. If
config.bRepeated is 0, the channel is set to single capture mode, otherwise to repeated capture mode.
The radio CPU sets the input source to config.inputSrc and the input mode to config.inputMode. If the
channel is set in single capture mode, it is also armed. This causes a channel event to occur when
capture happens, and can be enabled as an RF hardware interrupt to the system CPU through the
RFC_DBELL module.
CMD_SET_RAT_CMP may be sent as a direct command. If so, bits 2–15 of the config word are given by
bits 2–15 of CMDR (bits 0–1 of config are not used).
The channel number must indicate a channel that is not reserved for use by the radio CPU. Otherwise, the
radio CPU returns ParError in CMDSTA. If the channel is successfully set up, the radio CPU returns Done
in CMDSTA.
23.3.4.12 CMD_DISABLE_RAT_CH: Disable RAT Channel
Command ID number: 0x0408
CMD_DISABLE_RAT_CH is an immediate command that takes the parameters listed in
Byte Index Field Name
0–1 commandNo
2 ratCh
On reception, the radio CPU disables the RAT channel given by ratCh. This disables previous
configurations of that channel done by CMD_SET_RAT_CMP or CMD_SET_RAT_CPT.
CMD_DISABLE_RAT_CH may be sent as a direct command. If so, ratCh is given by the parameter in bits
8–15 of CMDR.
The channel number must indicate a channel that is not reserved for use by the radio CPU. Otherwise, the
radio CPU returns ParError in CMDSTA. If the channel number is valid, the CPU returns Done in
CMDSTA after the channel has been disabled.
