7.11.3 GPMC/NAND Flash Interface Asynchronous Timing

CAUTION

The I/O Timings provided in this section are valid only for some GPMC usage modes when the corresponding Virtual I/O Timings or Manual I/O Timings are configured as described in the tables found in this section.

Table 7-30 and Table 7-31 assume testing over the recommended operating conditions and electrical characteristic conditions below (see Figure 7-19, Figure 7-20, Figure 7-21 and Figure 7-22).

  1. GNF12 parameter illustrates amount of time required to internally sample input Data. It is expressed in number of GPMC functional clock cycles. From start of read cycle and after GNF12 functional clock cycles, input data will be internally sampled by active functional clock edge. GNF12 value must be stored inside AccessTime register bits field.
  2. GPMC_FCLK is an internal clock (GPMC functional clock) not provided externally.
  3. In gpmc_csi, i = 0 to 7. In gpmc_waitj, j = 0 to 1.

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.

Virtual IO Timings Modes must be used to ensure some IO timings for GPMC. See Table 7-2Modes Summary for a list of IO timings requiring the use of Virtual IO Timings Modes. See Table 7-32Virtual Functions Mapping for GPMC for a definition of the Virtual modes.

Table 7-32 presents the values for DELAYMODE bit field.

  1. Some signals listed are virtual functions that present alternate multiplexing options. These virtual functions are controlled via CTRL_CORE_ALT_SELECT_MUX or CTRL_CORE_VIP_MUX_SELECT registers. For more information on how to use these options, see Pad Configuration Registers section, Control Module chapter in the device TRM..
