(1) For single read: A = (CSRdOffTime – CSOnTime) * (TimeParaGranularity + 1) * GPMC_FCLK period

For burst read: A = (CSRdOffTime – CSOnTime + (n – 1) * PageBurstAccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK period

For burst write: A = (CSWrOffTime – CSOnTime + (n – 1) * PageBurstAccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK period

with n being the page burst access number.

(2) B = ClkActivationTime * GPMC_FCLK

(3) For single read: C = RdCycleTime * (TimeParaGranularity + 1) * GPMC_FCLK

For burst read: C = (RdCycleTime + (n – 1) * PageBurstAccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK

For burst write: C = (WrCycleTime + (n – 1) * PageBurstAccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK with n being the

page burst access number.

(4) For single read: D = (RdCycleTime – AccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK

For burst read: D = (RdCycleTime – AccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK

For burst write: D = (WrCycleTime – AccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK

(5) For single read: E = (CSRdOffTime – AccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK

For burst read: E = (CSRdOffTime – AccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK

For burst write: E = (CSWrOffTime – AccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK

(6) For nCS falling edge (CS activated):

–

Case GpmcFCLKDivider = 0:

–

F = 0.5 * CSExtraDelay * GPMC_FCLK

–

Case GpmcFCLKDivider = 1:

–

F = 0.5 * CSExtraDelay * GPMC_FCLK if (ClkActivationTime and CSOnTime are odd) or (ClkActivationTime and CSOnTime

are even)

–

F = (1 + 0.5 * CSExtraDelay) * GPMC_FCLK otherwise

–

Case GpmcFCLKDivider = 2:

–

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

–

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

–

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

(7) For ADV falling edge (ADV activated):

–

Case GpmcFCLKDivider = 0:

–

G = 0.5 * ADVExtraDelay * GPMC_FCLK

–

Case GpmcFCLKDivider = 1:

–

G = 0.5 * ADVExtraDelay * GPMC_FCLK if (ClkActivationTime and ADVOnTime are odd) or (ClkActivationTime and

ADVOnTime are even)

–

G = (1 + 0.5 * ADVExtraDelay) * GPMC_FCLK otherwise

–

Case GpmcFCLKDivider = 2:

–

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

–

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

–

G = (2 + 0.5 * ADVExtraDelay) * GPMC_FCLK 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

–

Case GpmcFCLKDivider = 1:

–

G = 0.5 * ADVExtraDelay * GPMC_FCLK if (ClkActivationTime and ADVRdOffTime are odd) or (ClkActivationTime and

ADVRdOffTime are even)

–

G = (1 + 0.5 * ADVExtraDelay) * GPMC_FCLK otherwise

–

Case GpmcFCLKDivider = 2:

–

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

–

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

–

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

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

–

Case GpmcFCLKDivider = 0:

–

G = 0.5 * ADVExtraDelay * GPMC_FCLK

–

Case GpmcFCLKDivider = 1:

–

G = 0.5 * ADVExtraDelay * GPMC_FCLK if (ClkActivationTime and ADVWrOffTime are odd) or (ClkActivationTime and

ADVWrOffTime are even)

–

G = (1 + 0.5 * ADVExtraDelay) * GPMC_FCLK otherwise

–

Case GpmcFCLKDivider = 2:
