A. In gpmc_csn[x], x is equal to 0, 1, 2, 3, 4, or 5. In gpmc_wait[x], x is equal to 0 or 1.
B. 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.
C. GPMC_FCLK is an internal clock (GPMC functional clock) not provided externally.
