Specifications

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

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.

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.

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