  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 bitfield for each corresponding pad control register.

The pad control registers are presented in Table 4-27 and described in Device TRM, Control Module Chapter.

Virtual IO Timings Modes must be used to ensure some IO timings for GPMC. See Table 5-28Modes Summary for a list of IO timings requiring the use of Virtual IO Timings Modes. See Table 5-54Virtual Functions Mapping for GPMC for a definition of the Virtual modes.

Table 5-54 presents the values for DELAYMODE bitfield.

  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, please refer to Device TRM, Chapter Control Module, Section Pad Configuration Registers.
