9.2.3. PTP Asymmetry Delay Reconfiguration Interface

Table 78.  PTP Asymmetry Reconfiguration InterfaceThe signals in this interface are clocked by the i_reconfig_clk clock and reset by the i_reconfig_reset signal of the PTP tile adapter. This clock and reset are used for all the reconfiguration interfaces in the IP core.
