Manual IO Timings Modes must be used to ensure some IO timings for GMAC. See Table 5-30Modes Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 5-104Manual Functions Mapping for GMAC RMII0 for a definition of the Manual modes.
Table 5-104 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers.
