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 the Control Module chapter in the Device TRM.
Manual IO Timings Modes must be used to ensure some IO timings for MMC2. See Table 7-2Modes Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 7-114Manual Functions Mapping for MMC2 With Internal Loopback Clock and for HS200 for a definition of the Manual modes.
Table 7-114 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers.
