The dwell time for AEQ to wait for lock or error-free status is also programmable. When checking each EQ setting the AEQ will wait for a time interval, controlled by the ADAPTIVE_EQ_RELOCK_TIME field in the AEQ_CTL2 register (See Table 184) before incrementing to the next allowable EQ gain setting. The default wait time is set to 2.62 ms based on REFCLK = 25 MHz. When the maximum setting is reached and there is no lock acquired during the programmed relock time, the AEQ will restart adaption at minimum setting or AEQ_FLOOR value.
