17.7.3. Auxiliary Transmit (ATX) PLL Calibration
ATX calibration tunes the parameters of the ATX PLL for optimal performance. This function runs once after power up. You can rerun this function by writing into the appropriate memory-mapped registers.
The RX buffer is unavailable while this function is running. You should run the ATX calibration after reconfiguring the PLL. You may need to rerun ATX calibration if you reset an ATX PLL and it does not lock after the specified lock time.
For more information about the Auxiliary Transmit (ATX) PLL Calibration refer to ATX PLL Calibration Registers.
Refer to the Parameterizing the Transceiver Reconfiguration Controller IP Core in the MegaWizard Plug-In Manager section for information about how to enabled these functions.
