23.3.4.9 CMD_READ_RFREG: Read RF Core Register
Command ID number: 0x0601
CMD_READ_RFREG is an immediate command that takes the parameters listed in
Byte Index Field Name
0–1 commandNo
2–3 address
4–7 value
On reception, the radio CPU reads the RF core register with address 0x4004 0000 + address. The result
is written to value. If the address is not divisible by 4, the radio CPU returns ParError in CMDSTA.
CMD_READ_RFREG may be sent as a direct command. If so, the address is given by bits 2–15 of
CMDR, with the two LSBs of the address set to 00.
When reading has been performed, the result is returned in value. The 24 LSBs of the result are returned
in CMDSTA bits 8–31. The result returned in CMDSTA is Done.
23.3.4.10 CMD_SET_RAT_CMP: Set RAT Channel to Compare Mode
Command ID number: 0x000A
CMD_SET_RAT_CMP is an immediate command that takes the parameters listed in
Byte
Field Name
Index
0–1 commandNo
2 ratCh
3
4–7 compareTime
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 hardware 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.
