(1) The internal parameters table must be used to calculate data access time stored in the corresponding CS register bit field.
(2) Internal parameters are referred to the GPMC functional internal clock which is not provided externally.
(3) GPMC_FCLK is general-purpose memory controller internal functional clock.
