NMONIC OPCODE
Function
Operation
SRXON
The ISRXON instruction immediately enables and calibrates frequency synthesizer for
RX. The instruction waits for the radio to acknowledge the command before executing
the next instruction.
Enable and calibrate freq.
synth. for RX
ISRXON
ISTXON
0xE2
0xE3
The ISTXON instruction immediately enables TX after calibration. The instruction waits
for the radio to acknowledge the command before executing the next instruction.
STXON_STRB
STXONCCA
Enable TX after calibration
The ISTXONCCA instruction immediately enables TX after calibration if CCA indicates
a clear channel. The instruction waits for the radio to acknowledge the command
before executing the next instruction.
Enable calibration and TX if
CCA indicates a clear channel
ISTXONCCA 0xE4
The ISRFOFF instruction immediately disables RX/TX and frequency synthesizer. The
instruction waits for the radio to acknowledge the command before executing the next
instruction.
ISRFOFF
0xE5
FFCTL_SRFOFF_STRB = 1
Disable RX/TX and freq. synth.
ISFLUSHRX instruction flushes the RXFIFO buffer and resets the demodulator. The
instruction waits for the radio to acknowledge the command before executing the next
instruction. Note that for compete flush the command must be run twice.
Flush RXFIFO buffer and reset
demodulator
ISFLUSHRX 0xE6
ISFLUSHTX 0xE7
SFLUSHRX
SFLUSHTX
SACK
ISFLUSHTX instruction immediately flushes the TXFIFO buffer. The instruction waits
for the radio to acknowledge the command before executing the next instruction.
Flush TXFIFO buffer
The ISACK instruction immediately sends an acknowledge frame. The instruction
waits for the radio to receive and interpret the command before executing the next
instruction.
Send acknowledge frame with
pending field cleared
ISACK
0xE8
The ISACKPEND instruction immediately sends an acknowledge frame with pending
field set. The instruction waits for the radio to receive and interpret the command
before executing the next instruction.
Send acknowledge frame
when pending field set
ISACKPEND 0xE9
SACPEND
