Write CAL:
CAL_START=0
End of calibration
Wait for maximum 26 ms, or
Read CAL and wait until
CAL.CAL_COMPLETE=1
Start dual calibration
Either frequency register A or B is selected
Write RFMAIN:
RXTX = 0; F_REG = 0; RX_PD = 0; TX_PD = 1;
FS_PD = 0; CORE_PD=0; BIAS_PD=0;
Write FREQ_A, FREQ_B
Write CAL.CAL_DUAL = 1
Frequency registers A and B are both used
for RX mode (or both for TX mode)
Write CAL.CAL_START=1
Dual calibration is performed.
Result is stored in TEST0 and TEST2,
for both frequency A and B registers
Write CURRENT.VCO_CURRENT = RX current
Write PLL.REFDIV = RX reference divider
Write TEST6=0x1B
‘RX current’ is the VCO current to be
used in RX mode.
TEST6 = 0x3B if TX mode
Calibration time depends on the reference
frequency, see text.
