(1) For single read: A = (CSRdOffTime - CSOnTime) * (TimeParaGranularity + 1) * GPMC_FCLK(14)

For burst read: A = (CSRdOffTime - CSOnTime + (n - 1) * PageBurstAccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK(14)

For burst write: A = (CSWrOffTime - CSOnTime + (n - 1) * PageBurstAccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK(14)

With n being the page burst access number.

(2) B = ClkActivationTime * GPMC_FCLK(14)

(3) For single read: C = RdCycleTime * (TimeParaGranularity + 1) * GPMC_FCLK (14)

For burst read: C = (RdCycleTime + (n - 1) * PageBurstAccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK(14)

For burst write: C = (WrCycleTime + (n - 1) * PageBurstAccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK(14)

With n being the page burst access number.

(4) For single read: D = (RdCycleTime - AccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK(14)

For burst read: D = (RdCycleTime - AccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK(14)

For burst write: D = (WrCycleTime - AccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK(14)

(5) For single read: E = (CSRdOffTime - AccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK(14)

For burst read: E = (CSRdOffTime - AccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK(14)

For burst write: E = (CSWrOffTime - AccessTime) * (TimeParaGranularity + 1) * GPMC_FCLK(14)
