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

FA5 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 FA5 functional clock cycles, input data will be internally sampled by active functional clock

edge. FA5 value must be stored inside AccessTime register bits field.

GPMC_FCLK is an internal clock (GPMC functional clock) not provided externally.
