9.12.26 PLL_CF – Transceiver Center Frequency Calibration Control Register
9.12.27 PLL_DCU – Transceiver Delay Cell Calibration Control Register
8266A-MCU Wireless-12/09
This register controls the operation of the calibration loop of the filter tuning network.
• Bit 7 – FTN_START - Start Calibration Loop of Filter Tuning Network
FTN_START = 1 initiates the calibration of the filter tuning network. When the
calibration cycle has finished after at most 25 µs the register bit is automatically reset to
0.
• Bit 6:0 – Resx6:0 - Reserved
This register controls the operation of the center frequency calibration loop.
• Bit 7 – PLL_CF_START - Start Center Frequency Calibration
PLL_CF_START = 1 initiates the center frequency calibration. The calibration cycle has
finished after 35 µs (typical). The register bit is cleared immediately after finishing the
calibration.
• Bit 6:0 – Resx6:0 - Reserved
