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, see Control Module chapter in the device TRM.
Manual IO Timings Modes must be used to ensure some IO timings for MMC3. See Table 7-2Modes Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 7-140Manual Functions Mapping for MMC3 for a definition of the Manual modes.
Table 7-140 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers.

NOTE
To configure the desired virtual mode the user must set MODESELECT bit and DELAYMODE bit field for each corresponding pad control register.
The pad control registers are presented in Table 4-3 and described in Device TRM, Control Module Chapter.
