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.
GPMC_FCLK is an internal clock (GPMC functional clock) not provided externally.
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 Table 4-29 and described in Device TRM, Control Module section.
