SWRS037B – JANUARY 2006 – REVISED MARCH 2015
summarizes the SPI address space. Registers that are only defined on the CC1101
transceiver are also listed. CC1101 and CC1150 are register compatible, but registers and fields only
implemented in the transceiver always contain 0 in CC1150.
The address to use is given by adding the base address to the left and the burst and read/write bits on the
top. Note that the burst bit has different meaning for base addresses above and below 0x2F.

STROBE NAME
DESCRIPTION
0x30
SRES
Reset chip.
0x31
SFSTXON
Enable and calibrate frequency synthesizer (if MCSM0.FS_AUTOCAL=1).
0x32
SXOFF
Turn off crystal oscillator.
0x33
SCAL
Calibrate frequency synthesizer and turn it off (enables quick start). SCAL can be strobed in
IDLE state without setting manual calibration mode (MCSM0.FS_AUTOCAL=0)
0x35
STX
Enable TX. Perform calibration first if MCSM0.FS_AUTOCAL=1.
0x36
SIDLE
Exit TX and turn off frequency synthesizer.
0x39
SPWD
Enter power down mode when CSn goes high.
0x3B
SFTX
Flush the TX FIFO buffer.
0x3D
SNOP
No operation. May be used to pad strobe commands to two bytes for simpler software.
