(1)

For single read: A = (CSRdOffTime - CSOnTime) × (TimeParaGranularity + 1) × GPMC_FCLK(18)

For burst read: A = (CSRdOffTime - CSOnTime + (n - 1) × PageBurstAccessTime) × (TimeParaGranularity + 1) × GPMC_FCLK(18)

For burst write: A = (CSWrOffTime - CSOnTime + (n - 1) × PageBurstAccessTime) × (TimeParaGranularity + 1) × GPMC_FCLK(18)

With n being the page burst access number.

(2)

B = ClkActivationTime × GPMC_FCLK(18)

(3)

For single read: C = RdCycleTime × (TimeParaGranularity + 1) × GPMC_FCLK(18)

For burst read: C = (RdCycleTime + (n - 1) × PageBurstAccessTime) × (TimeParaGranularity + 1) × GPMC_FCLK(18)

For burst write: C = (WrCycleTime + (n - 1) × PageBurstAccessTime) × (TimeParaGranularity + 1) × GPMC_FCLK(18)

With n being the page burst access number.

(4)

For single read: D = (RdCycleTime - AccessTime) × (TimeParaGranularity + 1) × GPMC_FCLK(18)

For burst read: D = (RdCycleTime - AccessTime) × (TimeParaGranularity + 1) × GPMC_FCLK(18)

For burst write: D = (WrCycleTime - AccessTime) × (TimeParaGranularity + 1) × GPMC_FCLK(18)

(5)

For single read: E = (CSRdOffTime - AccessTime) × (TimeParaGranularity + 1) × GPMC_FCLK(18)

For burst read: E = (CSRdOffTime - AccessTime) × (TimeParaGranularity + 1) × GPMC_FCLK(18)

For burst write: E = (CSWrOffTime - AccessTime) × (TimeParaGranularity + 1) × GPMC_FCLK(18)

(6)

For csn falling edge (CS activated):

– Case GpmcFCLKDivider = 0:

– F = 0.5 × CSExtraDelay × GPMC_FCLK(18)

– Case GpmcFCLKDivider = 1:

– F = 0.5 × CSExtraDelay × GPMC_FCLK(18) if (ClkActivationTime and CSOnTime are odd) or (ClkActivationTime and CSOnTime are

even)

– F = (1 + 0.5 × CSExtraDelay) × GPMC_FCLK(18) otherwise

– Case GpmcFCLKDivider = 2:

– F = 0.5 × CSExtraDelay × GPMC_FCLK(18) if ((CSOnTime - ClkActivationTime) is a multiple of 3)

– F = (1 + 0.5 × CSExtraDelay) × GPMC_FCLK(18) if ((CSOnTime - ClkActivationTime - 1) is a multiple of 3)

– F = (2 + 0.5 × CSExtraDelay) × GPMC_FCLK(18) if ((CSOnTime - ClkActivationTime - 2) is a multiple of 3)

(7)

ADVOnTime are even)

– G = (1 + 0.5 × ADVExtraDelay) × GPMC_FCLK(18) otherwise

– Case GpmcFCLKDivider = 2:

– G = 0.5 × ADVExtraDelay × GPMC_FCLK(18) if ((ADVOnTime - ClkActivationTime) is a multiple of 3)

– G = (1 + 0.5 × ADVExtraDelay) × GPMC_FCLK(18) if ((ADVOnTime - ClkActivationTime - 1) is a multiple of 3)

– G = (2 + 0.5 × ADVExtraDelay) × GPMC_FCLK(18) if ((ADVOnTime - ClkActivationTime - 2) is a multiple of 3)

For ADV rising edge (ADV deactivated) in Reading mode:

– Case GpmcFCLKDivider = 0:

– G = 0.5 × ADVExtraDelay × GPMC_FCLK(18)

– Case GpmcFCLKDivider = 1:

– G = 0.5 × ADVExtraDelay × GPMC_FCLK(18) if (ClkActivationTime and ADVRdOffTime are odd) or (ClkActivationTime and

ADVRdOffTime are even)

– G = (1 + 0.5 × ADVExtraDelay) × GPMC_FCLK(18) otherwise

– Case GpmcFCLKDivider = 2:

– G = 0.5 × ADVExtraDelay × GPMC_FCLK(18) if ((ADVRdOffTime - ClkActivationTime) is a multiple of 3)

– G = (1 + 0.5 × ADVExtraDelay) × GPMC_FCLK(18) if ((ADVRdOffTime - ClkActivationTime - 1) is a multiple of 3)

– G = (2 + 0.5 × ADVExtraDelay) × GPMC_FCLK(18) if ((ADVRdOffTime - ClkActivationTime - 2) is a multiple of 3)

(8)

For ADV rising edge (ADV deactivated) in Writing mode:

– Case GpmcFCLKDivider = 0:

– G = 0.5 × ADVExtraDelay × GPMC_FCLK(18)

– Case GpmcFCLKDivider = 1:

– G = 0.5 × ADVExtraDelay × GPMC_FCLK(18) if (ClkActivationTime and ADVWrOffTime are odd) or (ClkActivationTime and

ADVWrOffTime are even)

– G = (1 + 0.5 × ADVExtraDelay) × GPMC_FCLK(18) otherwise

– Case GpmcFCLKDivider = 2:

– G = 0.5 × ADVExtraDelay × GPMC_FCLK(18) if ((ADVWrOffTime - ClkActivationTime) is a multiple of 3)

– G = (1 + 0.5 × ADVExtraDelay) × GPMC_FCLK(18) if ((ADVWrOffTime - ClkActivationTime - 1) is a multiple of 3)
