• Bit 7 – PLL_DCU_START
PLL_DCU_START = 1 initiates the delay cell calibration. The calibration cycle has
finished after maximum of 6 µs. The register bit is cleared immediately after the register
write operation.
• Bit [6:0] – Reserved
9.8 Automatic Filter Tuning (FTN)
The filter-tuning unit is a separate block within the AT86RF230. The filter-tuning result is
used to provide a correct SSBF transfer function and PLL loop-filter time constant
independent of temperature effects and part-to-part variations.
A calibration cycle is initiated automatically when entering the TRX_OFF state from the
SLEEP, RESET or P_ON states.
