(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 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 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)
Case GpmcFCLKDivider = 3:

F = (3 + 0.5 * CSExtraDelay) * GPMC_FCLK if ((CSOnTime - ClkActivationTime - 3) is a multiple of 4)
(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)
