The associated registers to configure are listed in the CFG REGISTER column. For more information see the Control Module chapter in the Device TRM. Manual IO Timings Modes must be used to ensure some IO timings for GMAC. See Table 7-2 Modes Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 7-88 Manual Functions Mapping for GMAC RGMII0 for a definition of the Manual modes. Table 7-88 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers. Table 7-88.

See Table 7-2 Modes Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 7-89 Manual Functions Mapping for GMAC RGMII1 for a definition of the Manual modes. Table 7-89 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers. |
