Register 0x1A (PLL_CF)
The register PLL_CF controls the operation of the center frequency calibration loop.
• Bit 7 – PLL_CF_START
PLL_CF_START = 1 initiates the center frequency calibration. The calibration cycle has
finished after a maximum of 80 µs. The register bit is cleared immediately after the
register write operation.
• Bit [6:0] – Reserved
Register 0x1B (PLL_DCU)
The register PLL_DCU controls the operation of the delay cell calibration loop.
