NO. | PARAMETER | DESCRIPTION | MIN | MAX | UNIT |
---|---|---|---|---|---|
DDR1 | fop(clk) | Operating frequency, mmc2_clk | 48 | MHz | |
DDR2H | tw(clkH) | Pulse duration, mmc2_clk high | 0.5 × P-0.172 (1) | ns | |
DDR2L | tw(clkL) | Pulse duration, mmc2_clk low | 0.5 × P-0.172 (1) | ns | |
DDR5 | td(clk-cmdV) | Delay time, mmc2_clk transition to mmc2_cmd transition | 2.9 | 7.14 | ns |
DDR6 | td(clk-dV) | Delay time, mmc2_clk transition to mmc2_dat[7:0] transition | 2.9 | 7.14 | ns |
NOTE
To configure the desired virtual mode the user must set MODESELECT bit and DELAYMODE bitfield for each corresponding pad control register.
The pad control registers are presented in Table 4-32 and described in Device TRM, Control Module Chapter.
Virtual IO Timings Modes must be used to ensure some IO timings for MMC2. See Table 5-29Modes Summary for a list of IO timings requiring the use of Virtual IO Timings Modes. See Table 5-143Virtual Functions Mapping for MMC2 for a definition of the Virtual modes.
Table 5-143 presents the values for DELAYMODE bitfield.

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 5-29Modes Summary for a list of IO timings requiring the use of Manual IO Timings Modes. See Table 5-144Manual Functions Mapping for MMC2 for a definition of the Manual modes.
Table 5-144 lists the A_DELAY and G_DELAY values needed to calculate the correct values to be set in the CFG_x registers.
