GPMC_14

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_CSn[i], i is equal to 0, 1, 2 or 3. In GPMC_WAIT[j], j is equal to 0 or 1.
