RF Core HAL
On reception, the radio CPU sets the RAT channel given by ratCh in compare mode, and sets the channel
compare time to compareTime, which also arms the channel. A channel event occurs at the given time,
and this can be enabled as an RF HW interrupt to the system CPU through the RFC_DBELL module.
compare time to compareTime, which also arms the channel. A channel event occurs at the given time,
and this can be enabled as an RF HW interrupt to the system CPU through the RFC_DBELL module.
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 compare time is in the past when the command is
evaluated, the radio CPU returns ContextError in CMDSTA and disables the RAT channel. If the compare
event is successfully set up, the radio CPU returns Done in CMDSTA.

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 HW interrupt to the system CPU through the RFC_DBELL
module.
