GPMC_WAIT[j], j 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.

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

B. FA21 parameter
illustrates amount of time required to internally
sample first input page data. It is expressed in
number of GPMC functional clock cycles. From start
of read cycle and after FA21 functional clock
cycles, first input page data will be internally
sampled by active functional clock edge. FA21
calculation must be stored inside AccessTime
register bits field.
C. FA20 parameter
illustrates amount of time required to internally
sample successive input page data. It is expressed
in number of GPMC functional clock cycles. After
each access to input page data, next input page
data will be internally sampled by active
functional clock edge after FA20 functional clock
cycles. FA20 is also the duration of address
phases for successive input page data (excluding
first input page data). FA20 value must be stored
in PageBurstAccessTime register bits field.
D. GPMC_FCLK is an
internal clock (GPMC functional clock) not
provided externally.
