Description
0x30
SRES
0x30 SRES Reset chip.
0x31
SFSTXON
Enable and calibrate frequency synthesizer (if MCSM0.FS_AUTOCAL=1). If in RX (with CCA):Go
to a wait state where only the synthesizer is running (for quick RX / TX turnaround).
0x32
SXOFF
Turn off crystal oscillator.
0x33
SCAL
Calibrate frequency synthesizer and turn it off. SCAL can be strobed from IDLE mode without
setting manual calibration mode (MCSM0.FS_AUTOCAL=0)
0x34
SRX
Enable RX. Perform calibration first if coming from IDLE and MCSM0.FS_AUTOCAL=1.
0x35
STX
In IDLE state: Enable TX. Perform calibration first if MCSM0.FS_AUTOCAL=1.
If in RX state and CCA is enabled: Only go to TX if channel is clear.
0x36
SIDLE
Exit RX / TX, turn off frequency synthesizer and exit Wake-On-Radio mode if applicable.
0x38
SWOR
Start automatic RX polling sequence (Wake-on-Radio) as described in Section 19.5 if
WORCTRL.RC_PD=0.
0x39
SPWD
Enter power down mode when CSn goes high.
0x3A
SFRX
Flush the RX FIFO buffer. Only issue SFRX in IDLE or RXFIFO_OVERFLOW states.
0x3B
SFTX
Flush the TX FIFO buffer. Only issue SFTX in IDLE or TXFIFO_UNDERFLOW states.
0x3C
SWORRST
Reset real time clock to Event1 value.
0x3D
SNOP
No operation. May be used to get access to the chip status byte.
