NOTE
To configure the desired Manual IO Timing Mode the user must follow the steps described in section "Manual IO Timing Modes" of the Device TRM.
The associated registers to configure are listed in the CFG REGISTER column. For more information please see the Control Module Chapter in the Device TRM.
Manual IO Timings Modes must be used to guarantee some IO timings for GMAC. See Table 5-28, Modes Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 5-105, Manual Functions Mapping for GMAC RMII0 for a definition of the Manual modes.
Table 5-105 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers.

Manual IO Timings Modes must be used to guarantee some IO timings for GMAC. See Table 5-28, Modes Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 5-106, Manual Functions Mapping for GMAC RMII1 for a definition of the Manual modes.
Table 5-106 list the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers.
